I think the correct reaction is:
H2O + H+ -> H3O+
H2O -> OH- + H+
= 2 H2O -> H3O+ + OH-
I think you're looking at it backwards when you talk about "breaking" bonds. There's an
equilibrium between neutral water molecules and ions. Bonds are constantly forming and breaking spontaneously.
There's no energy change in the
population of molecules/ions - i.e. no heat flow in or out of the beaker of water. Therefore, thermodynamic calculations on whether or not a bond can "break" are irrelevant.
