WebMar 8, 2024 · If delta H and delta S are both positive, then whether the reaction is spontaneous or not is dependent on the T. When T (delta S) is greater than delta H, delta G is negative and therefore spontaneous. When T (delta S) is less than delta H, delta G is positive and therefore not spontaneous. WebA reaction with a negative D G is called exergonic to emphasize this. Conversely, a reaction with a positive value of D G is reactant-favored and requires the input of energy to go.
