In terms of energy, how would you classify the following chemical reaction? 2cuo + 315 kj → 2cu + o2
a. exothermic
b. endothermic
c. both endothermic and exothermic
d. neither endothermic nor exothermic

The reaction 2CuO + 315 kJ → 2Cu + O2 is an endothermic reaction.  (Option B)

Explanation: In order to determine what type of reaction is occurring above, you need to know that if heat is being released then it is an exothermic reaction. It can be determined if it would be on the product side. Whilst, if the heat is being absorbed, it would be an endothermic reaction and it would be on the side of the reactants.
