Van t'Hoff Law

Relation between the equilibrium constant and the variation of enthalpy in a reaction. With its integral, it is possible to calculate its equilibrium constant KT using the one at K298 (temperature of 298K).

Formula

\mathbf{\frac{\textrm d\ln(K_T)}{\textrm dT}=\frac{\Delta_\textrm rH^{\circ}_T}{R.T^2}} where KT is the equilibirum constant at temperature T, ΔH enthalpy variation and R the perfect gas constant.
