Question

If E = 10^4 and MH = 10, the nature of reaction is ____

(a) First order

(b) Second order

(c) Pseudo first order

(d) Negative order

This question was addressed to me in an interview for job.

Asked question is from Design of Fluid Fluid Reactors in chapter Fluid-Fluid Reactions: Kinetics & Basics of Non Ideal Flow of Chemical Reaction Engineering

Answer 1

Correct option is (c) Pseudo first order

The explanation is: E > 5MH. The reaction proceeds by pseudo first order mechanism at the interface as 10^4 > 10.
