Difference Between Enthalpy and Entropy

WebFeb 20, 2024 · Enthalpy is a measure of the total energy contained within a system, while entropy is a measure of the disorder or randomness of the system. The two are related because when a reaction occurs, the enthalpy of the system decreases and the entropy increases. This is known as the entropy-enthalpy compensation principle.
