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.
A day is added to February every four tears as a corrective measure. The Earth does not exactly revolve around the sun for 365 days. There is a small offset that is corrected by adding a day to February. This happens every four years and it is called Leap year.
It might be more suitable because some data cannot use a graph to show data because there is too much data.
