How do you know if a reaction will be favored forward, reverse, or neither?

Question

What's Delta G?

Answer 1

if the delta G of the reaction is negative the reaction is spontaneous left to right. If delta G is positive it is not spontaneous left to right an d in fact the reverse reaction is favored ...right to left.

If delta G is 0  then neither right nor left is favored the equation is at equilibrium.
