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 right
B. Lower the E and shift equilibrium to the right
C. Lower the E and shift equilibrium to the left
D. Increase the E and shift equilibrium to the left

Answer

A

Explanation

`Zn_((s))+2H_((aq))^(+)hArrZn_((aq))^(2+)+H_(2(g))`
`E_(cell)=E_(cell)^(o)-(0.059)/(2)"log"([Zn^(2+)])/([H^(+)]^(2))`
When `H_(2)SO_(4)` is added then `[H^(+)]` will increase therefore `E_(cell)` will also increase and equilibrium will shift towards right.
