Question

State true or false.

An exothermic reaction approaches isothermal conditions by increasing the addition of inerts to the reaction mixture.

(a) An exothermic reaction approaches isothermal conditions by increasing the addition of inerts to the reaction mixture.

(b) True

(c) False

This question was addressed to me in a job interview.

The above asked question is from RTD for Chemical Reactors topic in portion Distribution of Residence Time for Chemical Reactors of Chemical Reaction Engineering

Answer 1

Correct choice is (a) An exothermic reaction approaches isothermal conditions by increasing the addition of inerts to the reaction mixture.

To explain: For an exothermic reaction, HR < 0. Addition of inerts causes the the curve of conversion and temperature to shift to isothermal conditions.
