An irreversible Isomerizationreaction AR is carried out in a liquid phase in MFR. Thereaction is first order and the rate constant at 165oC is 0.7 hr-1. The activation energy of thereaction is 120 kJ/mol and the heat of reaction is -350 kJ/kg. The heat capacity of thereactants and products are 1.95 kJ/kg-K, the volumetric flow rate is 0.33 m3/hr, and the feedtemperature is 20oC. If the conversion is 95%, calculate
(a) the reactor size and
(b) the temperature of the reaction mixture, if the reactor is operated adiabatically
Calculate the specific heat capacity and the molar heat capacity of mercury.
Wet air containing 4.0mole% water vapor is passed through a column of calcium chloride pellets. The pellets adsorb 97.0% of the water and none of the other constituents of the air. The column packing was initially dry and had a mass of 3.40kg, fol..
During the research that led to production of the two atomic bombs used against Japan in World War II, different mechanisms for obtaining a supercritical mass of fissionable material were investigated.
The pressure of a sample of gas at a constant temperature of 25 degrees C is increased from 1.0 atm to 1.2 atm. If the original volume was 3.8 liters, what will the new volume be?
The maximum possible purity of glycol in the finished extract and the maximum purity of water in the raffinate for one equilibriumstage.
Discuss the characteristics of this microenvironment.
The lower flammable limit (LFL) of methanol in air is 6.0 mole%. Calculate the temperature at which the equilibrium percentage of methanol vapor in a saturated methanol-air mixture would equal the LFL. (This temperature is a rough estimate of the ..
Two beds are used, with one in operation and one in regeneration. If the bed is designed to be 80% loaded at the end of a 2 hour operation cycle, estimate the bed volume. Also determine the flow rate of sodium hydroxide required during the regener..
two important allotropes of elemental phosphorus are white phosphorus and red phosphorus a. why should gloves be worn
Consider a diatomic gas, N2, at 298 K. This gas is compressed reversibly and adiabatically from 15 dm3 to 5.0 dm3. Assume that the heat capacity of this gas is CV=5R/2, and that it behaves ideally. Calculate the final temperature, T2, of the gas.
Steam enters a cooling tower at 200 °C and exits at 60 °C. Cooling is supplied by the surroundings which are assumed to be at 30 °C. The process takes place under atmospheric pressure (1 bar).
Calculate the molarity of each of these solutions. a. A 5.623-g sample of NaHCO3 is dissolved in enough water to make 250.0 mL of solution. b. A 184.6-mg sample of K2Cr2O7 is dissolved in enough water to make 500.0 mL of solution.
