# Can gibbs free energy be negative?

##### 1 Answer

Yes, the Gibbs free energy can be negative or positive or zero.

All reactions are in principle equilibria.

If the position of equilibrium lies far to the right, we say that the reaction goes to completion. We then write the equation with a single arrow (→).

If the position of equilibrium lies far to the left, we say that there is no reaction.

The Gibbs free energy is related to the position of equilibrium.
