Question

Effect of flow type on reactor performance when the conversion is small.

(a) no effect

(b) cannot be determined

(c) very small

(d) very large

This question was addressed to me in an interview.

The origin of the question is Choosing of Right Reactor Series or Connections (Maximum Profitability) topic in chapter Ideal Reactors for a Single Reaction, Conversion and Reactor Sizing of Chemical Reaction Engineering

Answer 1

Right answer is (c) very small

To explain: The reactor performance is not affected by flow type when the conversion is small. If the conversion is very high, flow type largely affects the reactor performance.
