Van't Hoff vs Le Chatelier's principle
Can someone provide a simplified explanation of the correlation between Van't Hoff and Le Chatelier's principle please.

Hi,
Both Van't Hoff's principle and Le Chatelier's principle provide insights into how changes in temperature affect the equilibrium of a reaction, with Van't Hoff's principle focusing on the quantitative change in the equilibrium constant and Le Chatelier's principle focusing on the qualitative shift in the equilibrium position.

Re: Van't Hoff vs Le Chatelier's principle
The V'ant Hoff equation demonstrates the temperature dependence of K, so it shows how when T changes, the value of K also changes. This relates to Le Chatelier's principle because with a change in temperature, Le Chatelier's principle tells us that when only temperature (heat) increases in an endothermic reaction, more products will be made despite there being the same concentrations of the products/reactants. This is why the K value changes with a change in temperature. But because a temperature change isn't really a physical change we can see or add, the V'ant Hoff equation can help better represent and understand how that temperature increase results in a change in K.
