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

A

lower the E and shift equilibrium to the left

B

increases 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

Text Solution

Verified by Experts


Addition of `H_2SO_4` will increase `[H]^(+)` and `E_("cell")` will also increase and the equilibrium will shift toward right .
