`Pt |{:((H_(2))),(1atm):}:| pH = 2:|:|:pH =3 |:{:((H_(2))Pt),(1atm):}:|`. The cell reaction for the given cell is:-

Options

A. Spontaneous
B. non-spontaneous
C. Equilibrium
D. none of these

Answer

B

Explanation

`H_(2)to2H_((10^(-2)M))^(+)+2e^(-)`
`2H_((10^(-3)M))^(+)+2e^(-)toH_(2)`
`2H_((10^(-3)M))^(+)to2H_((10^(-2)M))^(+)`
`E=0-(0.0591)/(2)log((10^(-1))/(10^(-2)))^(2)`
`Etove` (non spontaneous).
