Question

According to Lewis and Whitman theory, the departure from concentration equilibrium at the Interphase is due to

(a) Low mass transfer rates

(b) High mass transfer rates

(c) Moderate mass transfer rate

(d) None of the mentioned

I had been asked this question by my college director while I was bunking the class.

My enquiry is from Interphase Mass Transfer in portion Interphase Mass Transfer of Mass Transfer

Answer 1

The correct choice is (b) High mass transfer rates

Explanation: Theoretically proved by Lewis and Whitman, that if the mass transfer rates are higher the concentration deviates from equilibrium.
