Use standard free energies of formation to calculate ΔG∘ at 25∘C for each of the following reactions.

NOBr(g)→NO(g)+1/2Br2(l)

NH4I(s)→HI(g)+NH3(g)

3H2(g)+Fe2O3(s)→2Fe(s)+3H2O(g)

NO(g)+1/2O2(g)→NO2(g)

Question-4 (40%)

A 75-hp (shaft output) motor that has an efficiency of 91.0 percent is worn out and is to be replaced by a high efficiency motor that has an efficiency of 95.4 percent. The motor operates 4368 hours a year at a load factor of 0.75. Taking the cost of electricity to be $0.12/kWh, determine:

a) the amount of energy (kWh/year) and money ($/year) saved as a result of installing the high-efficiency motor instead of the standard motor. (20 points)

b) the simple payback period (in months) if the purchase prices of the standard and high-efficiency motors are $5449 and $5520, respectively. (10 points)

c) If the life of the motor is 2 years, is it cost effective to buy 91.0% efficiency motor or 95.4% efficiency motor? Explain. (10 points)

Service Department Charges

In divisional income statements prepared for LeFevre Company, the Payroll Department costs are charged back to user divisions on the basis of the number of payroll distributions, and the Purchasing Department costs are charged back on the basis of the number of purchase requisitions. The Payroll Department had expenses of $58,380, and the Purchasing Department had expenses of $22,000 for the year. The following annual data for Residential, Commercial, and Government Contract divisions were obtained from corporate records:

a. Determine the total amount of payroll checks and purchase requisitions processed per year by the company and each division.

b. Using the activity base information in (a), determine the annual amount of payroll and purchasing costs charged back to the Residential, Commercial, and Government Contract divisions from payroll and purchasing services. If required, round your answers to two decimal places. Do not round your interim calculations, round your answers to two decimal places, if required.

c. Residential's service department charge is   than the other two divisions because Residential is a   user of service department services. Residential has many employees on a weekly payroll, which translates into a   number of check-issuing transactions.

Describe how Aeneas illustrates the values of Rome and societal expectations for behavior. How do different episodes in Aeneas' journey illustrate Roman ideals and also Roman superiority?
The Romans celebrated their culture and beliefs with columns and friezes, for example. Consider how the Roman-style architecture in such cities as London, Paris, Toronto, Washington, D.C. help bring Aeneas to the present time.

After a workforce has been recruited and developed, managers and human resource management (HRM) professionals must maintain an effective workforce. In a short essay, explain the significance of an effective reward system to maintaining a workforce. Suppose you are the manager of a company. What kind of optional and mandatory benefits would you offer as part of your rewards package? What type of employee compensation system would you use? Why?

Problem 1. One of the consequences of ethanol addiction is fatty liver disease, an illness in which liver cells accumulate large amounts of triacylglycerols, the esters derived from glycerol and fatty acids. Ethanol is oxidized in the cytoplasm of liver cells by alcohol dehydrogenase and aldehyde dehydrogenase to yield acetate and 2 NADH. Acetate is then transported into the mitochondrion, where it is converted to acetyl-CoA and metabolized in the citric acid cycle.

1. Give a reason based on the products of ethanol metabolism and the electron transport chain for high energy charge in the cell
2. How would excess G6P concentration contribute to the reducing potential required for fatty acid synthesis?
3. How does acetate stimulate the rate of citrate formation based on enzyme kinetic?
4. How would the concentration of citrate in the mitochondria increase if the rate of isocitrate dehydrogenase rate were inhibited
5. What would inhibit the rate of isocitrate dehydrogenase if ethanol metabolism causes high-energy charge.
