You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: If ΔG° is negative for a reaction, then … 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. ウェブスマイルログイン

WebThe Gibbs free energy of a reaction dictates where a reaction is spontaneous (-ΔG) or nonspontaneous (+ΔG). This is due to the components of the free energy equation (ΔG = ΔH -TΔS) that add up to be negative or positive.
