Question: Consider the following reaction: O 3 ( g ) + NO( g ) NO 2 ( g ) + O 2 ( g ) E

Consider the following reaction:

O3(g) + NO(g) NO2(g) + O2(g) Ea = 11.90 kJ mol-1

A catalyst is added to the reaction mixture that lowers the activation energy to 7.7 kJ mol-1.

By what ratio will the reaction rate constant change (kwith catalyst / kwithout catalyst) at 295 K?
