We can use the measured equilibrium constant K at one temperature, along with ΔH° to estimate the equilibrium constant for a reaction at any other temperature.
Heterogeneous Mixture The most important consideration for a heterogeneous mixture is that solids and pure liquids and solvents have an activity that has a fixed value of 1.
In contrast, the magnitude and sign of ΔS° affect the magnitude of K but not its temperature dependence.
