## Vant Hoff Equation

$\Delta G^{\circ}= \Delta H^{\circ} - T \Delta S^{\circ}$

$\Delta G^{\circ}= -RT\ln K$

$\Delta G^{\circ}= \sum \Delta G_{f}^{\circ}(products) - \sum \Delta G_{f}^{\circ}(reactants)$

### Vant Hoff Equation

Will we be given the Vant Hoff equation for the test? I can't find it on the posted equation sheet

Hi! It isn't anything new in particular, it's just a combination of ∆G° = - RT ln K and ∆G° = ∆H° - T∆S°. You don't need to memorize it as long as you can make those equations equal to each other.

### Re: Vant Hoff Equation

When do we know when to use the Vant Hoff equation?

It depends on what you are given but most of the time if you are trying to find K but you're given delta H and delta S (or vice versa)
