Other corrections to equilibrium constants

Many of the equilibrium constants reported in the literature are reported at a temperature of 298.15 K. However, as many reactions in the environment will occur at different temperatures, it is important to be able to estimate what the value of K will be at the temperature of interest. This can be done using the Van Hoff equation  

In the computer program MINTEQA2 in addition to using the Van Hoff equation there is the option of using a power function of the form
