Vant Hoff Equation

How would you use the Vant Hoff Equation when there are two different temperatures given?
Do you solve for one temperature first and then the other and add them?

Re: Vant Hoff Equation

Hi, Cristina,
You can use van't Hoff equation with two different temperatures, as it contains (1/T1 - 1/T2) variable.
Van't Hoff equation is used only to compare two equilibrium constants at two different temperatures.
