Equilibrium constant (Given temperature and enthalpy change, Van 't Hoff equation)

Formula

Equilibrium constant (Given temperature and enthalpy change, Van 't Hoff equation) formula
K2
equilibrium constant at T1
T2
the corresponding temperautre
T1
the temperature at anther point
K1
the corresponding equilibrium constant at the known temperature T1
DeltaHo
the standard enthalpy change

Formula description

The van 't Hoff equation in chemical thermodynamics relates the change in temperature to the change in the equilibrium constant given the standard enthalpy change for the process. This can be used to predict the temperature at a certain equilibrium constant, given the temperature at another equilibrium constant, or vice versa.
