1 the probability of dissociation of water into h

Question

1. The probability of dissociation of water into H⁺ and OH^- , to a good approximation, can be characterized by the Boltzmann distribution:

 W ≈ e^{-Eα/ KT}

If, at 27°C, 1.5 moles of water contain 1.5 X 10¹³ pairs of H⁺ and OH^- , estimate the value of energy of dissociation.
