Question

The present CSTR is replaced by another CSTR of double the volume. A first order liquid phase reaction occurs in both the reactors. If the conversion achieved in the old reactor is 75%, what is the conversion achieved in the new reactor?

(a) 0.857

(b) 0.675

(c) 0.765

(d) 0.99

I had been asked this question in homework.

I need to ask this question from Conversion and Reactor Sizing topic in chapter Ideal Reactors for a Single Reaction, Conversion and Reactor Sizing of Chemical Reaction Engineering

Answer 1

Correct option is (a) 0.857

Explanation: \(\frac{0.75}{X_A} = \frac{0.25}{2(1-XA)} \)

XA = 0.857.
