Designing a Nonisothermal BR

The following gas phase reaction is operated in a nonisothermal variable volume batch reactor:

The conditions of the reacting fluid and the chemical reactor are given as follows:

C_A0 = 0.5 mol/ L

C_B0 = 0.6 mol/L

C_pA = C_pB= 65 J /mol × K

C_pC= 150 J / mol × K

ΔH_r(T) = -15 kJ/mol

n_A0= 100 mol

UA = 50 J / s × K

in mol / L × s

Using polymath or any suitable software, answer the following questions:

1. What is the time needed to reach a conversion of 0.80 for the following cases:
   1. Isothermal operation.
   2. Adiabatic operation with feed temperature of 300 K.
   3. Nonadiabatic operation with a coolant supply sufficient to maintain the reactor wall at 300K.
2. With a feed at T = 300 K, plot the temperature profiles and conversion profiles for three different values of coolant the temperature. What can you conclude?

Note:  Plotting x vs. time and T vs. time are required for all cases.
