Gibbs Free and Direction of Reaction

Postby VioletKo3F » Wed Mar 04, 2020 12:29 am

If Gibbs is positive and spontaneous, why does it mean that it will produce more reactants?

that's a good question haha! i've just always remembered that negative delta g means the reverse reaction is spontaneous and the reactants are favored, but i've never really thought about it before. i hope someone can answer! :)

When Gibbs Free Energy is negative, it is spontaneous. When it's positive, it will produce more reactants, because it will not occur as easily as it would with spontaneous reactions.

When delta G(naught) is positive then more reactants are present than products at equilibrium and vice versa when it is negative.
