SUMMARY
The enthalpy of ionization for the weak acid, ΔH3, can be calculated using Hess's law, based on the provided reactions. The values obtained for ΔH1 and ΔH2 are -52.33 kJ/mol and -5.21 kJ/mol, respectively. To find ΔH3, one must manipulate the reactions to eliminate the hydroxide ion (OH-) and water (H2O) from the equations. This involves starting with the second reaction and applying the first reaction appropriately to derive the desired enthalpy change.
