equilibrium constants and free energy [ENDORSED]

[Maddy_Larson_2J]

When K=0 what does this mean in terms of free energy?

[Timothy_Yu_Dis3A]

If the equilibrium constant = 0 and K = [Products]/[Reactants], then there are no products that form during the reaction. I don't think the equilibrium constant can ever reach 0 though because the Gibbs Free Energy is defined by G = -RTlnK, and ln(0) would be undefined. However, if the equilibrium constant were close to 0, then the reaction would strongly favor the reactants and so the Gibbs Free Energy would be very positive because the forward reaction is highly unfavorable.
