when it is zero, neither the forward nor the reverse reaction is spontaneous.

when it is zero, both the forward and reverse reaction are spontaneous.

when it is positive, the forward reaction is spontaneous but the reverse is not.

when it is negative, the reverse reaction is spontaneous but the forward is not.
