Basic results of chemical thermodynamics

As the partial pressure is proportional to the nfole fraction for perfect-gas mixtures, (P /atm) X (P/atm), and so 

This equation applies not only to equilibria involving gases but also to equilibria in solution, and indeed to any equilibrium when the equilibrium constant is expressed in terms of mole fractions rather than partial pressures. In these circumstances AF is the volume change accompanying one mole of reaction.  

A famous physical chemist, G. N. Lewis, once stated Thermodynamics exhibits no curiosity . By this he meant that the conclusions of thermo-
