First order, irreversible, exothermic liquid phase reaction in a jacketed CSTR.

The cooling rate is 2500 cal/s. Moreover, the work due to the agitator may not be neglected. The agitator (shaft) work is 240 cal/s.

The reaction A + B 2C

There is no product in the feed stream.

Specific heat of the reactants and product are 15 cal/(mol.K).

Heat of reaction is -22,000 cal/mol and is assumed to be constant.

The concentrations of A and B in the feed stream are 0.07 mol/L.

The feed temperature is 20 oC. The volumetric flowrate of feed is 3.2 L/s.

The rate constant k at 20 oC is 0.025 L/(mol.s) and the activation energy is 11,000 cal/mol.

The conversion of A is 90%

(a) Calculate the temperature in the reactor

(b) Calculate the volume of the reactor
