The reduction potential of hydrogen half...

The reduction potential of hydrogen half cell will be negative if :

A

`P_(H_(2))=1 "atm" and [H^(+)]=1.0 M`

B

`P_(H_(2))=2 "atm" and [H^(+)]=2.0 M`

C

`P_(H_(2))=2 "atm" and [H^(+)]=1.0 M`

D

`P_(H_(2))=1 "atm" and [H^(+)]=2.0 M`

Text Solution

Verified by Experts

The correct Answer is:
C
`2H^(+)+2e^(-) to H_2`
`therefore RP=0.0-(0.059)/2 "log" (P_(H_2))/([H^+]^2)`
