Using Van't Hoff

[Avantika MOhan_2B]

We've now learned of a few different ways to calculate K (equilibrium constant) with temperature change. Is Van't Hoff only used when we have an enthalpy value? What could we use instead?

When we want to see how temperature affects the equilibrium constant K, we often use the Van't Hoff equation, especially if we know the enthalpy change ΔH^o of the reaction. But if we don't have that information, we can still figure it out. One way is by looking at how the reaction quotient Q changes with temperature. We can also do experiments at different temperatures to directly see how K changes. And if we're feeling fancy, we can use complex computer simulations to predict it. So, whether we have ΔH^o or not, there are ways to figure out how temperature shakes things up in chemical reactions.
