(A) . At equilibrium,the rate of the forward reaction is equal to the rate of the backward reaction.
$b$. If $\Delta G < 0$ (negative),the reaction is spontaneous and proceeds in the forward direction.
$c$. The equilibrium constant provides information regarding the extent of the reaction (i.e.,how far the reaction proceeds towards the products).
