For an endothermic reaction, the value for ΔE_rxn is a negative number.

Question

Quizplus · Accepted Answer

For an endothermic reaction, ΔH (enthalpy) is positive, meaning energy is absorbed. However, ΔS (entropy) is also positive, meaning the disorder of the system increases. The value for ΔE_rxn, which includes both ΔH and ΔS, can thus be positive or negative depending on the magnitudes of the two values and the temperature at which the reaction occurs.
