Textbook Problem

Use the equation in Exercise 79 to determine ∆H° and ∆S° for the autoionization of water:

H 2 O ( l ) H + ( a q ) + OH - ( a q )

T(°C) KW
0 1.14×10−15
25 1.00×10−14
35 2.09×10−14
40. 2.92×10−14
50. 5.47×10−14

Interpretation Introduction

Interpretation: The values of ΔHοandΔSο for the auto ionization of water are to be determined.

Concept introduction: The standard enthalpy and entropy change are the thermodynamic functions. The superscript on these functions represents the standard form. The term Δ represents the change. The relation between the enthalpy and entropy change of with the Gibb’s free energy change is given by a mathematical formula.




The reaction is given as,


From the exercise 79 it is clear that there is a straight line plot between the lnKVs1T .

Therefore, from the given values of rate constant and time the values of lnK and inverse of time is tabulated as,


The relation between the equilibrium constant with entropy and enthalpy is given as,



  • K is equilibrium constant.
  • R is gas constant.
  • ΔHο is enthalpy change.
  • ΔSο is enthalpy change.
  • T is temperature in Kelvin
