Question

The unit for rate of reaction for a fluid-solid catalytic reaction is _______

(a) mol/m^3.s

(b) mol/s. g catalyst

(c) mol/s. mmHg

(d) mol/dm^3.s

The question was posed to me in class test.

The origin of the question is Mole Balances in chapter Basic Concepts of Chemical Reaction Engineering

Answer 1

Correct answer is (b) mol/s. g catalyst

Explanation: Rate of reaction for a fluid-solid catalytic reaction is defined as the number of moles of A reacted per unit time per unit mass of catalyst.
