### Van't hoff equation

Since the Van T hoff equation is not given in the formula booklet, would we have to memorize it?

We are expected to know how to derive the Van't Hoff Equation so it is not explicitly on the formula sheet, but the two main equations we need to know in order to derive the Van't Hoff Equation are both on the formula sheet!

You can memorize it, or learn how to derive it from the two delta G equations. Delta G = -RTlnK and Delta G = deltaH - T(deltaS). Set both equations to each other and you can derive the Van't Hoff equation.
