For the chemical reactionthe energy contained in the reactants is 352 kJ, and the energy contained in the products is 394 kJ.

Question

Assuming 1 mol of each substance is present. How much energy is either absorbed or released during the reaction?

42 kJ is absorbed, and the reaction is endothermic.

42 kJ is released, and the reaction is endothermic.

42 kJ is absorbed, and the reaction is exothermic.

42 kJ is released, and the reaction is exothermic.

Answer 1

42 kJ is absorbed, and the reaction is endothermic.
