How can the spontaneity of reaction determine by the value of DeltaG^0

1.	How can the spontaneity of reaction determine by the value of DeltaG^0 ?
Answer» Solution :`DeltaG LT 0` , i.e., negative So, REACTION is forward and products increase and K `gt` 1. `DeltaG gt 0`, i.e., POSITIVE, So, reaction is reverse and products decreases and K `lt` 1. `DeltaG = 0`, i.e., ZERO, So, reaction is in equilibrium and reaction is not occurs in any direction and K=1.
