For the equilibrium, 2H(2)O hArr H(3)...

For the equilibrium,
`2H_(2)O hArr H_(3)O^(+) + OH^(-)`,the value of `DeltaG^(@)`at 298 K is approximately:

A

`-80 KJ mol^(-1)`

B

`8xx10^(-12) M`

C

`8xx10^(-13) M`

D

`8xx10^(-11) M`

Text Solution

Verified by Experts

The correct Answer is:
B

For the equilibrium `2H_(2)O to H_(3)O^(=) + OH^(-)`
`DeltaG^(0)=-RT lnK_(eq.) K_(eq)=1xx10^(-14)`
`=-2.303xx298xx8.314xxlog10^(-10)=80KJ//mol`
