For reaction AB+C⇌A+BCAB+C \rightleftharpoons A+BC, the activation energy for the forward reaction is 10 kJ/(mol·rxn)–1. When we increase the temperature until the average collision energy of the particles is larger than 10 kJ/mol, there are still collisions between AB and C that are not successful reactions. Why not?
