What happens when K<1, and Gibbs free energy is a positive value, assuming P and R are in their standard states?

K < 1 implies that at a given temp, the reactants are more favored than products, and thus the forward reaction to form more products is unfavorable.

This is confirmed by a Positive Delta G, which tells us that the forward reaction is not spontaneous (endergonic), and needs energy/work input to be driven forward

I think Dr. Lavelle also mentioned that when K<1, enthalpy dominates over entropy, and the reaction will be non-spontaneous

In a general sense, why are we looking at the K value when solving problems with Gibbs free energy?
