is the activation energy for an exothermic reaction smaller than that off an endothermic one?

Question

chmvijay · Answer

yaa true !!!bcoz the relesed energy can be utilised to decrease the activation energy!!!

foolaroundmath · Answer

Not necessarily. Activation energy has very little to do with whether a reaction is endothermic or exothermic. Activation energy only represents the difference in energy of the transient state and the initial state.
