Question

On the basis of the following thermochemical data :
$[\Delta_fH^0 (H^+_{(aq)}= 0)]$
$H_2O(l) \rightarrow H^+(aq) + OH^-(aq)$; $\Delta H$ = 57.32kJ
$H_2(g) + \frac{1}{2}O_2(g) \longrightarrow H_2O(l)$; $\Delta H$ = - 286.20kJ
The value of enthalpy of formation of OH⁻ ion at 25° C is:
(a) –228.88 kJ
(b) +228.88 kJ
(c) –343.52 kJ
(d) –22.88 kJ

Answer 1

(c) part is the correct option
