In a cell that untillizes the reaction ,
`Zn_((s)) + 2 H_((aq))^+ rarr Zn_((aq.))^(2+) + H_(2 (g) )`, adedition of ` H_2 SO_4` to cathode compartment will :

Options

A. increase tha E and shift equilibrium to the left.
B. lower the E and shipt equilibrium to the right.
C. increase the E and shift equilibrium to the right.
D. lower the E and shift equilibrium to the left.

Answer

C

Explanation

`E_(cell)=E_(cell)^(0)+(0.059)/(1)log.([H^(+)]^(2))/(P_(H_(2))xx[Zn^(2+)])`
Addition of `H_(2)SO_(4)` will increase `[H^(+)]` and thus `E_(cell)` will be more and equilibrioum will shift to right,
