### reaction profile

are the activation energies for the forward and reverse reactions ever equivalent?

### Re: reaction profile

They are only ever equivalent when the reaction is in equilibrium

maybe it could be possible if the potential gibbs free energy of the reactants is equal to the potential gibbs free energy of the products. but it is probably super rare

### Re: reaction profile

Generally, the activation energies for a forward and reverse reaction will be different if the reaction is not at equilibrium because one reaction will be endothermic and the other will be exothermic, so each side requires a different amount of energy.
