Question

State true or false.

The Arrhenius law plot of lnk vs 1/ T gives a straight line with large slope for large activation energy.

(a) True

(b) False

I have been asked this question during an interview.

This intriguing question originated from Reaction Kinetics Elements in portion Elements of Reaction Kinetics of Chemical Reaction Engineering

Answer 1

Right choice is (a) True

For explanation: The plot of lnk vs 1/ T gives a straight line of slope –\(\frac{E_a}{(R×T)}\). As Ea increases, slope increases.
