"WebIf ΔG is negative, the products have less free energy than the reactants and so the reaction speeds up the forward reaction to create more products (since reactions want to minimize their free energy). If ΔG is positive, then the reactants have less free energy than the products and the reverse reaction speeds up to create more reactants. " - If g is negative for a reaction
