In a cell that utilizes the reactions.
`Zn(s) + 2H^(+) (aq) rightarrow Zn^(2+)(aq) + H_(2)(g)`
addition of `H_(2)SO_(4)` to cathode compartment, will

Options

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

Answer

C

Explanation

`Zn(s)+2H^(+)(aq)rarrZn^(2+)(aq)+H_(2)(g)`
`Zn|Zn^(2+)||H^(+)|H_(2),Pt`
Increasing `[H^(+)]` will shift the equilibrium to the right. It will also increase `[H^(+)]` will shift the equilibrium to the right. It will b e also increase `3_(2H)^(@)._(//H2)` i.e. `E_("right")`.
