|\,\,\,\,\,\,\,\,\,\,\,\,\,|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, \\
OH\,\,\,\,\,\,\,{{C}_{2}}{{H}_{5}}\,\,\,\,\,\,\,\,\,\,\, \\
\end{matrix}$ is
→From the following thermochemical equations, find out the heat of ionisation $Z$ for a weak acid $HA$
$HA \to A^- + H^+ \,,\, \Delta H = Z$
$H^+ + OH^-\to H_2O\,, \, \Delta H = X$
$HA + OH^-\to A^-+ H_2O\,, \, \Delta H = Y$
