The oxidation potential of hydrogen half-cell will be negative if :

Answer»

`p(H_2) =1 ATM and [H^+] = 1M`
`p(H_2)= 1 atmand [H^(+)] = 2M`
`p(H_2) = 0.2 atm and [H^(+)] = 1M`
`p(H_2) = 0.2 atm and [H^(+)]=0.2 M`

SOLUTION :`E_(RP) = E_(0)^(0) -(0.0591)/(2) log""(PH_2)/((H^(oplus))^(2)) , 2H^(oplus) + 2e^(-) IMPLIES H_2`
` -E _(OP)= + (0.0591)/(2) log""((H^(oplus))/(P_(H_2)))`
a) `E_(RP )= -E(OP) = 0 ` b) `E_(RP) = -E_(OP) = +ve ` c) `E_(RP) = -E_(OP) = +ve` d) `E_(RP) = -E_(OP) = -ve`
