Gibbs Free Energy and Spontaneity

Postby Jared Smith 1E » Sun Feb 11, 2018 10:44 pm

So I know that when delta G is negative, the forward reaction is spontaneous. Is it then correct to assume that whenever delta G is positive, the reverse reaction is spontaneous?

Yes I believe so.

Yes with a positive deltaG, the reaction is not spontaneous in the forward direction but will be spontaneous if reversed.
With a negative deltaG, the reaction IS spontaneous in the forward direction but not so if reversed.
