3. A key step in the production of sulfuric acid is the oxidation of SO2(g) to SO3(g):

2SO2(g) + O2(g) ----------> 2SO3(g)

At 298K, G= -141.6kJ; H=-198.4kJ; and S=-187.9J/K

a) Us the date to decide if this reaction is spontaneous at 25deg Cand predict how G will change with increasing T.

b) Assuming DH and DS are constant with increasing T, is the reaction spontaneous at 900deg C?

c) If the reaction reaches the equilibrium , calculate the temp.

Toolkit Exercise 10.3

Application of Simon’s Control Systems Model

Consider a change you are familiar with (higher education change).

1.      Describe the control processes and measures that were used with the change (i.e., the belief, interactive, boundary, and diagnostic controls). When and how were they used and what was their impact?

      a.    During the earlier stages of the change initiative

      b.    During the middle stages of the change initiative

      c.    During the latter stages of the change initiative

2.      Were there forbidden topics in the organization, such as questions related to strategy or core values? Were those limits appropriate and did anyone test those limits by raising controversial questions or concerns? Were small successes celebrated along the way?

3.      What changes could have been made with the control processes and measures that would have assisted in advancing the interests of the change?

Identify possible challenge stressors and the hindrance stressors that could be affecting your team members. Is it possible for the same stressor to be a challenge stressor to one person and a hindrance stressor to another? Explain your answer, please.

Please answer questions in the order listed. You do not need to be completely correct, but I do need to see an honest effort. For this post, YOU MUST SHOW YOUR WORK, on any question requiring math. This is to make it so that I can see where exactly where you mis-stepped in your calculation or logic, and/or so that your classmates can learn from you.

5.) MicroServe needs $100,000 to upgrade its warehouse. Dayna, the CEO of MicroServe, thinks they can put off the upgrade for 5 years. The company will make 5 annual deposits to fund this expansion. If the account earns 8% interest, how much does Dayna need to deposit every year? (Round your answers to the nearest dollar and show your work!!!)

Lab 9: Phone Call

Write a program that will calculate the cost of a phone call as follows:

1. The first 10 minutes are charged at a flat rate of $0.99 (Not 99 cents a minute - but 99 cents for the first 10 minutes or less).
2. This means that a phone call of 1 minute or 6 minutes or 10 minutes will be charged the same flat rate of 99 cents.
3. Every minute after the initial 10 minutes will be charged at $0.10 per minute.
4. Input the number of minutes talked as an integer.
5. Using an IF/ELSE structure, check for an entry of 0 minutes first, and inform the User that no minutes were entered.
   
   • IF 0 minutes are entered THEN
     • output an error message stating that no minutes were entered.
   • ELSE
     • Calculate and display the results.
     • The final display will show the minutes and the final cost.
     • The price will be formatted with 2 decimal places.
   • END IF

Include all Prologue information with your program

• Include an Initial Algorithm
• Include Input, Output, and Formulas (if any)
• Include a Refined Algorithm
• Test your program thoroughly with the following data:

1. 9 minutes
2. 10 minutes
3. 11 minutes
4. 35 minutes
5. 0 minutes

NOTE 1:

• DO NOT use the "return 0" code, end, break, or exit to force an exit from within your IF/ELSE structure.  Declare all variables within the data declaration section.
  • Let the program progress to the end of the main function.
  • The end of the main function is the only place that the “return 0” should be placed.
  • A switch statement is the only place that the break command should be placed.
• DO NOT use the continue statement.

NOTE 2:

1. Declare all variables within the data declaration section of each class and method.  (-.1)
2   Do not get input on the same line as a variable declaration.  (-.1)
3. Do not place an equation for computation on the same line as declaring a variable.  (-.1)
4. Do not place an equation for computation on the same line as an input statement.  (-.1)
5. Do not place any computations within an output statement. (-.1)

Middler Corporation, a manufacturer of electronics and communications systems, uses a service department charge system to charge profit centers with Computing and Communications Services (CCS) service department costs. The following table identifies an abbreviated list of service categories and activity bases used by the CCS department. The table also includes some assumed cost and activity base quantity information for each service for October. CCS Service Category Activity Base Budgeted Cost Budgeted Activity Base Quantity Help desk Number of calls $96,750 2,500 Network center Number of devices monitored 660,250 9,500 Electronic mail Number of user accounts 71,000 7,100 Handheld technology support Number of handheld devices issued 142,400 8,900 One of the profit centers for Middler Corporation is the Communication Systems (COMM) sector. Assume the following information for the COMM sector: The sector has 2,000 employees, of whom 60% are office employees. Almost all office employees (90%) have a computer on the network. 95 percent of the employees with a computer also have an e-mail account. The average number of help desk calls for October was 1 calls per individual with a computer. There are 290 additional printers, servers, and peripherals on the network beyond the personal computers. All the nonoffice employees have been issued a handheld device. a. Determine the service charge rate for the four CCS service categories for October. Round your answers to two decimal places. CCS Service Category Service Charge Rate Help desk $ Per call Network center $ Per device monitored Electronic mail $ Per user or e-mail account Handheld technology support $ Per device b. Determine the charges to the COMM sector for the four CCS service categories for October. October charges to the COMM sector: Help desk charge $ Network center charge $ Electronic mail charge $ Handheld technology support $

Write a small assessment no more than 2 pages including mention above: Alternatives and improvements to refrigerators and freezers in Cape York Community.

Remote Indigenous communities rely on refrigeration and freezers to store large amounts of food over time, ensuring traditional hunting practices can be maintained and people can come and go from Country as needed. This project looks at mechanisms for freezing and storing food beyond the generic available appliances which are dependent on connection to a large, pre-existing solar power supply.

Include the following aspect in this report: write a professional and concise document which draws on appropriate background information. An assignment is well written, contains appropriate references and draws on suitable background information. consider the context of the engineering work including social, cultural, environmental and commercial factors. All required factors are considered with sufficient detail and analysis relevant to the proposed project. And there is evidence that standard engineering principles and practices have been applied to the development of the assignment. The document contains all required elements outlined in the task description including introduction, project objective and possible design criteria.

To test whether extracurricular activity is a good predictor of college success, a college administrator records whether students participated in extracurricular activities during high school and their subsequent college freshman GPA.

(a) Code the dichotomous variable and then compute a point-biserial correlation coefficient. (Round your answer to three decimal places.)
