Enthalpy is the energy contained inside a substance that can be transferred as h

Question

Enthalpy is the energy contained inside a substance that can be transferred as heat at constant pressure.

Entropy is a measure of the randomness or disorder in a system.

If ?G = 0, then the reaction is at equilibrium. If ?G > 0, the forward reaction is spontaneous. If ?G < 0,the reverse reaction is spontaneous.

Which statement about Gibbs free energy change, ?G, is not correct?

?G is an expression that shows how enthalpy and entropy contribute to the overall tendency of a reaction to occur.

Explanation / Answer

If ?G = 0, then the reaction is at equilibrium. If ?G > 0, the forward reaction is spontaneous. If ?G < 0,the reverse reaction is spontaneous.
