In a cell that utilises the reaction Zn_((s))+2H_((aq))^(+)toZn_((aq))^(2+)+H_(2(g)) addition of H_(2)SO_(4) to cathode compartment, will

Answer»

Increase the E and SHIFT EQUILIBRIUM to the right
Lower the E and shift equilibrium to the right
Lower the E and shift equilibrium to the left
Increase the E and shift equilibrium to the left

Solution :`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.
