Quizplus · Accepted Answer

The difference between $\Delta H$ and $\Delta E$ per mole of product for a reaction is zero when the reaction is carried out at constant volume, as both quantities refer to the heat of reaction. The difference arises in scenarios involving work done by expansion or compression at constant pressure, which is not specified in this question. Therefore, without additional information suggesting work being done, the difference is assumed to be zero.
