WebThe absolute value of the Gibbs free energy decreases as the spontaneous process happens. The negative value represents the spontaneity of expansion. The more negative (smaller) the G, the more work you can obtain from the system. So as work is done on the surroundings, G becomes closer to zero, and in this case increases. WebSolution. The reason for Gibb's free energy to be negative. When G is negative, the reaction is spontaneous and, can proceed in the forward direction but if the reaction is nonspontaneous it can proceed spontaneously in the reverse direction, and the reaction is non-spontaneous when Gibb's free energy is positive. Therefore Gibb's free energy ...
