The reaction of methylacetate with water is shown below:

CH3CO2CH3 (aq) + H2O (l) ? CH3CO2H (aq) + CH3OH (aq)

The rate of the reaction is given by the following rate law: rate = k[H+][CH3CO2CH3] Consider one liter of solution that is 0.15 M CH3CO2CH3 (aq) and 0.015 M H+ (aq) at 25?C (a) For each change listed below state whether the rate of reaction increase, decreases or remains the same. Why?

(i) methylacetate (CH3CO2CH3) is added to the solution

2. The temperature is lowered

3 Water is added to the solution

For those 3 cases does the K increase or remain the same?

4000 m3/d of wastewater with a total suspended solids (TSS) concentration of 200 mg/L is subjected to treatment by coagulation and flocculation followed by sedimentation. The ferric chloride dose is 25 mg/L and the TSS removal is 90%. Estimate the daily volume of sludge produced if the sludge has a specific gravity of 1.05 and moisture content of 92.5%. The following reaction is applicable: 2FeCl3 + 3Ca(OH)2 ? 2Fe(OH)3 + 3CaCl2

Provide comparison for liquid mixing expriments using different impellers and baffles and discuss how this affect the liquid and the power curves and power requirements.

In a furnace, 76 lbs propane C3H8 are burned with 17.2% excess air for complete combustion. What is the percent CO2 in combustion products? Round your answer to the one decimal place.

Cyclohexanol is a highly desired chemical precursor for the production of nylon (billions of
kilograms of cyclohexanol are produced annually!). Industrially, cyclohexanol can be formed by
the oxidation of cyclohexane over cobalt catalysts.
You have a vapor mixture of 50 mol.% cyclohexane and 50 mol.% cyclohexanol. You want to
cool and condense your vapor mixture to form a vapor product and a liquid product.
a. This problem contains a vapor-liquid system. Using the Gibbs phase rule, determine the
number of degrees of freedom in a vapor-liquid equilibrium.
b. Your vapor mixture fills a drum that is 300 L in volume. At atmospheric pressure and at
200°C, how many moles of vapor do you have?
c. You decide to feed your vapor mixture to the condenser at 5 mol/s. You measure your
vapor product and see that it comes out at 760 mmHg and 75 mol.% cyclohexane. Using
Raoult’s law and Antoine’s Equation, determine your outlet temperature.
d. Using the information given in the problem statement and Part C, determine the
composition of your liquid phase and the molar flow rates of both your liquid and vapor
products.

In a closed system with a mobile border, a wet vapor with X = 1 is contained. The system undergoes heating keeping the plunger at rest, however the pressure and temperature change to 2MPa and 800 ° c, respectively. Subsequently, the heating process continues at constant pressure until the system reaches a temperature of 1300 ° c, generating an expansion process.
a) estimate the initial pressure of the system
b) calculate the work done by the steam
c) calculate the total heat transferred to the water vapor
d) represent the process on a T-v diagram

Steam at 275ºC and 15.0 bar is contained in a rigid tank with the volume of 10.0 m3 . In a constantvolume cooling process, the pressure inside the tank drops to 1.8 bar and some of the steam condenses. Calculate 1) the temperature of the tank contents after the process, 2) the amount of steam condensed during the process (in kg), and 3) the amount of heat removed from the tank during the process.

An electron microscope focuses electrons through magnetic lenses to observe objects at higher magnification than is possible with a light microscope. For any microscope, the smallest object that can be observed is one-half the wavelength of the radiation used. Thus, for example, the smallest object that can be observed with light of 400.0 nm is 2.00 ×10⁻⁷ m.

(a) What is the smallest object observable with an electron microscope using electrons moving at

8.70 ×10⁴ m/s?

(b) At 1.40 × 10⁷ m/s?
