### Delta G rules

Can someone briefly explain the rules that apply to Delta G when it is less than, greater than, or equal to zero? (i.e its spontaneity)

when delta G is positive it is nonspontaneous, when it is negative it is spontaneous and if it equals 0 it is at equilibrium

The reaction is spontaneous when delta G is negative, nonspontaneous when delta G is positive, and at equilibrium when delta G is 0

And a negative enthalpy change and positive entropy change increase the spontaneity.

using the equation delta G=deltaH-T(delta S)

delta g>0 it is nonspontaneous. When delta g<0 it is spontaneous. And when it is equal to zero it is at equilibrium.

When delta G is less than zero it is spontaneous, more than zero it is not spontaneous, and equal to zero it is at equilibrium.

### Re: Delta G rules

Delta G > 0 ; Not spontaneous
Delta G < 0 ; Spontaneous
Delta G = 0 ; Equilibrium

Positive means non-spontaneous, Negative means spontaneous, and 0 means at equilibrium
