Question

In CSTR, the rate of reaction is evaluated at the exit conditions.

(a) True

(b) False

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

My question is taken from Design Equations for Flow Reactors topic in portion Ideal Reactors for a Single Reaction, Conversion and Reactor Sizing of Chemical Reaction Engineering

Answer 1

Right answer is (a) True

To explain I would say: The composition at exit is identical to the composition in the reactor. Hence, reaction rate is measured at the exit conditions.
