If the reaction quotient (Q) is greater than the equilibrium constant what does that indicate for Gibbs free energy?

Greater than 0 because it will be non spontaneous

Thanks!

To clarify if Q>K the reaction would want to shift in the reverse way to make more reactants in order to reach K. Since this will make the reverse rxn more favorable than the forward rxn, the forward rxn will not be spontaneous, and thus, delta G is 0.

That’s very helpful! Thanks again
