Q)

On the basis of the following thermo chemical data $ [ \Delta G_f^{\circ} (H^+ )(aq) = 0] $ \[\] $H_2O(l) \rightarrow H^+ (aq) + OH^-(aq);\: \: \: \: \: \Delta H = 57.32\: kJ $ \[\] $H_2(g) + \large\frac{1}{2} (g) \rightarrow H_2O(l); \: \: \: \: \: \: \Delta H = -286\: kJ$ \[\] The value of enthalpy of formation of $OH^-\: ion $ at $25^{\circ}C$ is

$\begin {array} {1 1} (A)\;-22.88\; kJ & \quad (B)\;-228.88\: kJ \\ (C)\;228.88 \: kJ & \quad (D)\;-343.52\: kJ \end {array}$
