underset(S^(@)(298K)K^(-1)mol^(-1))(H^(+)(aq))+underset(-10.7)(OH^(-)(aq))rarrunderset(+70)(H_(2)O(l)) Standard entropy change for the above reaction is

Answer»

`60.3 JK^(-1) MOL^(-1)`
`80.7 JK^(-1) mol^(-1)`
`-70 JK^(-1) mol^(-1)`
`+10.7 JK^(-1) mol^(-1)`

Solution :`underset(S^(@)(298K)K^(-)mol^(-))(H_((aq))^(+))+underset(-10.7)(OH_((aq))^(-))rarrunderset(+70)(H_(2)O_((l)))`
`DELTAS^(@)(298 K)=DeltaS_(P)-DeltaS_(R)=70-(-10.7+0)`
`80.7 JK^(-)mol^(-1)`
