For Pt(H(2))|H(2)O , reduction potential...

For `Pt(H_(2))|H_(2)O` , reduction potential at `298 K` and `1 atm` is `:`

A

`-0.2364V`

B

`-0.4137V`

C

`0.4137V`

D

`0.00V`

Text Solution

Verified by Experts

The correct Answer is:
c
Since oxidation occurs.
`H_(2) rarr 2H^(o+)+2e^(-)`
`Q=[H^(o+)]^(2)=10^(-14)M^(2) i n H_(2)O`
` E=E^(c-)-(0.0591)/(2)log10^(-14)`
`=0+0.0.591xx7=0.4137V`
