## Van't Hoff Equation

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

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

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

### Van't Hoff Equation

The equation is not listed on the formula sheet. Does this mean that we need to know how to derive the equation for the midterm?

### Re: Van't Hoff Equation

From my understanding the equation is not on the equation sheet but you should either memorize it or know how to derive it from the fact that
∆H - T∆S = -RT ln (K). It's pretty helpful for specific problems given K and ∆H, but I doubt you'll have to show the derivation if you do use the equation.

### Re: Van't Hoff Equation

I would memorize the equation, but it should be pretty simple to derive just in case you forget on the test.

### Re: Van't Hoff Equation

Based on the learning objectives listed for Chapter 9, it would be helpful to know how to derive the equation.
