If the pressure of hydrogen gas is increased from 1 atm. To 100 atm, keeping the hydrogen ion concentration constant at 1 M, the reduction potential of the hydrogen half cell is at 25^(@)C will be

Answer»

0.059 V
`-0.059V`
`0.295V`
`0.118V`

Solution :`E_(H_(2)//H^(+))=-(0.0591)/(1)log_(10)((sqrt(pH_(2)))/([H^(+)]))`,`H^(+)+e^(-)to(1)/(2)H_(2)`
