Final answer:
A positive ΔG' in a given reaction indicates that the reaction is not spontaneous. The free energy change will be positive, indicating a non-spontaneous reaction.
Step-by-step explanation:
A positive ΔG' in a given reaction indicates that the reaction is not spontaneous under the given conditions. It means that the products will have a higher free energy than the reactants at equilibrium. The reaction will not occur spontaneously in the forward direction.
For example, if the change in enthalpy (ΔH) is positive and the change in entropy (ΔS) is negative, the free energy change (ΔG) will be positive, indicating a non-spontaneous reaction.
