Problem

The potential energy profiles for three reactions are shown below.

Which of the following is a  true statement?

A) Endothermic rxns are always slower than exothermic rxns
B) The faster the rate of a reaction the more exothermic it must be
C) Ea of rxn 1 is 2 times that of rxn 3
D) For reaction 1, ΔHrxn = ‐70 k/mol
E) The Ea for the reverse reaction of rxn 2 is Ea2 = +30 kj/mol
