Answer:
When a system is at equilibrium, <u>the process is not spontaneous at either direction.</u>
Explanation:
The process is not spontaneous at either direction , when a system is at equilibrium ΔG = 0, because -
We know that a negative ΔG indicates a forward-moving phase that is random.
We already know that a positive ΔG implies a non-spontaneous phase going forward.
Thus , here ΔG = 0, so the process is not spontaneous in either direction.
