### Van't Hoff Equation

What are the different ways in which we can manipulate the equation? What are the primary applications of this formula?

### Re: Van't Hoff Equation

There are many ways to manipulate the equation, as you can manipulate the variables solve for dH, K2, K1, T2, and T1. The main use for the equation is to relate the change in K to the change in temperature.

You can derive this equation when solving for different temperature phases or k's. Mainly, we would try to find k2/k1.

I believe that the main use of the equation is to tell how K is affected by a change in temperature. That's how I've seen it used.

I think the main way we use this equation is to find the new equilibrium constant based on a change in temperature

### Re: Van't Hoff Equation

You use the van't Hoff equation to relate the equilibrium constant to a change in temperature. This can help you find a new equilibrium constant for the same reaction at a different temperature.

### Re: Van't Hoff Equation

You shouldn't really need to manipulate the equation too much. It is used to solve for K values for a certain recreation at different temperatures. So If you know the K at a certain temperature, you can use the equation to solve for K at another temperature.
