Heat of neutralisation of strong acid and strong base under `1 atm` and `25^@C` is `-13.7 kcal`. If standard Gibbs energy change for dissociation of water to `H^+` and `OH^-` is `-19.14 kcal`, the change in standard entropy for dissociation of water is:

Options

A. `18.25`
B. `110.2`
C. `-18.25`
D. none of these

Answer

A

Explanation

for `H_(2)O hArr T Delta S^(@) Delta H^(@)`
`Delta S^(@) = (Delta H^(@)-Delta G^(@))/(T)`
