in what situation would we use the Van't Hoff equation?

You would use this equation when you are trying to find out how a K value would change if you increased the temperature of a reaction (you would need to be given another K value at a lower or higher temp which is why there is K1/K2 and T1/T2).

Usually a Van't Hoff question will give you the reaction enthalpy and ask you to either find a K value from an original K and two temperatures, or a T value from and original T and 2 equilibrium constants.

you use Van't Hoff when you are trying to relate a K value to the increasing temperature T.

I have found that we use Vant Hoff when we are either given 2 temperatures and a K or two Ks and a temperature.

The vant hoff equation can be rearranged to find different values, such as G values, enthalpy, entropy, temperature, and K values

You use Vant Hoff when you are trying to find how K changes as temperature changes.

You can use this equation to find a lot of things depending on how you decide to rearrange the equation, but you know you need to use if the reaction involves a temperature change

The Van't Hoff equation would be used in order to determine the equilibrium constant as the temperature changes. Therefore, when you have two temperatures and two K values, one can use the Van't Hoff equation.

You would use the Van't Hoff equation when there is a temperature change and you are looking to find an equilibrium constant.

It would be used in a situation where you are trying to find a K value at a different temperature. For instance, on test 2, we were given the K value at one temp and we were asked to find the K value at a different temperature since the K value changes with temperature. In that situation, we would have to use the Van't Hoff equation.

The van 't Hoff equation can be used to explore the changes in state functions in a thermodynamic system
