## Equilibrium Values

isochoric/isometric: $\Delta V = 0$
isothermal: $\Delta T = 0$
isobaric: $\Delta P = 0$

### Equilibrium Values

At equilibrium, why is it that delta H, delta G, and delta S equals 0?
I wanted to clarify the reasoning behind each of these. Also, do these tie into their spontaneous positive or negative values?

delta S and delta H are not zero at equilibrium, only delta G is zero at equilibrium.

To further answer your question, when delta G is positive it is not spontaneous, when it is negative it is spontaneous.When Delta S total is positive the process is spontaneous, and when it is negative it is not spontaneous.
