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 the `E` and shift equilibrium to the left
B. lower the `E` and shift equilibrium to the right
C. increase by `E` and shift equilibrium to the right
D. lower the `E` and shift equilibrium to the left

Answer

C

Explanation

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