Liquid phase isomerization of o-xylene to p-xylene using a zeolite catalyst was carried out in a CSTR

Q. Liquid phase isomerization of o-xylene to p-xylene using a zeolite catalyst was carried out in a CSTR. Three sets of kinetic data at different temperatures and stirring speeds were obtained as shown below.

The operating condition at which the reaction rate is not controlled by external mass transfer resistance is

(A) T = 500 K; rpm = 3000

(B) T = 600 K; rpm = 1000

(C) T = 700 K; rpm = 1000

(D) T = 700 K; rpm = 2000

Ans: T = 500 K; rpm = 3000
