Problem 1
Consider the following reaction sequence.
a. What is (are) the active intermediate?
b. Provide a rate law for the product.
Problem 2
A second order reaction where ??→?? occurs in a CSTR under isothermal conditions. The exothermic reaction occurs at 175°C. A heat exchange fluid at 25°C is available.
The temperature of the reactants entering the reactor is 50°C and the heat of reaction is -15000 J/mol. The reaction rate constant is 0.005 m3/(mol/s). The heat capacity of A is 150 J/(mol/K) and its fractional conversion is 75%. The initial molar concentration of A is 300 mol/m3.
a. What is the initial molar flow rate of A if the volume is 10 m3?
b. What is the heat transfer area if the heat transfer coefficient is 1.5 KJ/(m2.°C.h)?
