Given that the reaction C(s) + O 2 (g) → CO 2 (g) is exothermic, which of the following is true of the reaction CO 2 (g) → C(s) + O 2 (g)?

The reverse reaction (CO 2 (g) → C(s) + O 2 (g)) is endothermic if the forward reaction is exothermic. Therefore, the activation energy for the reverse reaction is higher because it requires energy input to proceed.
