For the equilibrium,

2{H_2}O\underset{{}}{\overset{{}}{\leftrightharpoons}}{H_3}{O^ + } + O{H^ - }

, the value of

\Delta {G^ \circ }

at 298 K is approximately

View answer and explanation

Correct option: C

80\,kJ\mathrm{ }mo{l^{ - 1}}

Option C (

80\,kJ\mathrm{ }mo{l^{ - 1}}

) is correct because the Gibbs free energy change is related to the ion product of water (

K_w

) and can be calculated using the formula

\Delta G^\circ = -RT\ln K_w
