Van't Hoff Equation
I don't quite understand when and why I need to use this equation. What is its relevance to delta H? What is an example of the problem that utilizes this?

Re: Van't Hoff Equation
So essentially, the Van't Hoff Equation is used to calculate the equilibrium constant at different temperatures. The equation assumes a constant delta So and a constant delta Ho, as these standard values should not change based upon a temperature change. Thus, given K1 at temperature T1, you can use the Van't Hoff Equation to calculate K2 at any temperature T2 for a reaction. I hope that clarifies things!

Re: Van't Hoff Equation
Is the Van`t Hoff Equation related to the Arrhenius Equation, or am I totally off the mark? I remember seeing that equation but I thought it was the Arrhenius equation (A variataion or something of it).

Re: Van't Hoff Equation
I think that the best way to know when to use the Van't Hoff Equation is when you are given 2 equilibrium reactions at two different temperatures. It is part of the thermodynamics chapter and can be found on page 42 in the course reader.

Re: Van't Hoff Equation
Would there ever be a time when we are asked to calculate K but not given delta H? If so, then how would we solve for K?
