Abstract: According to the Free-Energy Functions the following approximate formula without heat capacity for equilibrium constant is suggested:lgKp= - (△H2980/4.576T)+ (△S2980/4.576)+a(T-298) where a = constant, obtained by use of only a single measurement of Kp.More than110 equilibrium constants of reactions have been calculated at different temperatures and the results obtained coincide very well with the experimental values.
