The Free Energy Change of a Reaction under Nonstandard Conditions [Pg.843]

We can calculate the free energy change of a reaction under nonstandard conditions (AGrxn) from AG°xn using the relationship [Pg.843]

A Spilled water spontaneously evaporates even though AG° for the vaporization of water is positive. Why [Pg.843]

A FIGURE 17.13 Free Energy versus Pressure for Water The free energy change for the vaporization of water is a function of pressure. [Pg.843]

Standard Conditions Under standard conditions, PhjO = 1 atm and therefore 2=1-Substituting, we get the expression [Pg.844]
