Abstract: The theoretical value of the equilibrium constant K^Ø is dimension-tess. In the equilibrium constant equation the relative pressure can be only used instead of "concentration" for the gas and the relative its theoretical value is equal to that laboratory value. By using the equation △rG_m^Ø=-RTlnK^Ø not only the equilibrium constant can be determined from the thermodynamic data, but also △rG_m^Ø can be calculated by the experimental value K.
