In this problem, they are asking us to determine whether or not a reaction is exothermic or endothermic. Can someone explain how you can use activation energies to indicate whether a reaction is endothermic or exothermic?

In an endothermic reaction, the activation energy of the forward reaction would be higher than the activation energy of the reverse reaction.

In an exothermic reaction, the activation energy of the reverse reaction would be higher than the activation energy of the forward reaction.
