Below are the potential energy profiles for three reactions. Which of the following statements is true?
The activation energy of Reaction 3 is thrice the activation energy of Reaction 1.
For Reaction 2, ΔHrxn = –65 kJ/mol.
The activation energy of the reverse reaction for Reaction 3 is Ea2 = +15 kJ/mol.
The more exothermic the reaction, the faster the reaction would be.
Exothermic reactions are always faster than endothermic reactions.
