Question

State true or false.

For pure gaseous reactants, the best reactor suited for carrying out reaction is CSTR.

(a) For pure gaseous reactants, the best reactor suited for carrying out reaction is CSTR.

(b) True

(c) False

I had been asked this question during an online exam.

This is a very interesting question from Conversion and Reactor Sizing in division Ideal Reactors for a Single Reaction, Conversion and Reactor Sizing of Chemical Reaction Engineering

Answer 1

The correct choice is (a) For pure gaseous reactants, the best reactor suited for carrying out reaction is CSTR.

Easy explanation: For pure gaseous reactants, \(\frac{C_p}{-∆H_r} \) is small, where Cp is the specific heat capacity of the gas and ∆Hr is the enthalpy change of reaction. CSTR gives a high conversion for small values of \(\frac{C_p}{-∆H_r}. \)
