Free Energy of Dilution

Calculate ?G for the dilution of aqueous HCl from 2.87 M to 0.148 M at 25C.

The process you are considering is:

H^{+}_{(aq)} + Cl^{-}_{(aq)}? H^{+}_{(aq)} + Cl^{-}_{(aq)} (for which ?G=0 i.e. standard states all round--both sides are the same).

Now use ?G=?G + RTln(Q). (Use the actual concentrations to determine Q).

Does this agree with what you intuitively know about the spontaneity of diffusion?
