Calculating an Equilibrium Constant from the Free Energy Change

If we know the standard state free energy change, DeltaGo, for a chemical process at some temperature T, we can calculate the equilibrium constant for the process at that temperature using the relationship between DeltaGo and K.

The equation for calculatiing delta G from the equilibirum constant

Rearrangement gives

ln K equals e to the minus Delta G over R T

In this equation:
