Concept behind Van't Hoff Equation

Postby Beatrice Petelo 1F » Sun Feb 17, 2019 3:05 pm

Why do we use the Van't Hoff equation? What does it tell us in terms of K and temperature?

We use the Van't Hoff to calculate K at different temperatures. This is important because K is dependent on temperature, so at different temperatures K has a different value.

In what situations would we need to calculate different temperatures?

The Van't Hoff Equation relates temperature change and K so you're able to calculate it if T of the system is changed.This temperature change can affect the equilibrium of the system so this can be used to examine that.

It helps to relate the effect of temperature on the equilibrium constant of a reaction. Back when we were looking at Le Chatelier's principle, we noticed that only a change in temperature changed our equilibrium constant as a whole, and this equation can be used to see how a change in temperature directly affects that value.

This equation helps us determine how a system behaves at equilibrium at a new temperature. The value of K itself changes, so you can really see if products or reactants are favored more or less than they were before!
