Van't Hoff Equation

Postby Helen Mejia 1I » Mon Feb 18, 2019 10:50 pm

Can someone explain why temperature is dependent on K in the Van't Hoff Equation?

K is just a constant in the equation that relates entropy and enthalpy in a system.
If you want to know more I suggest you look at the section in the thermodynamics tab called Van't Hoff Equation.

The intention of the van't Hoff equation is to confirm Le Chatelier's principle for the effect of temperature on K not the other way around. I think you want to think of K being dependent on temperature, not vice versa. According to the equation, a change in temperature of a certain amount changes K which does support Le Chatelier's principle.

K depends on temperature, K being when the system is at equilibrium. When a system is at equilibrium, deltaG equals zero.
