Question

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

Answer 1

if the thermal energy is written on the reactants side, then the reaction NEEDS the energy to go forward. This type of reaction is called ENDOthermic.

If the thermal energy is written on the products side, the reaction gives off heat. This type of reaction is called EXOthermic.

Answer 2

Then it's endothermic

Answer 3

then it is
