In a cell that utilizes the reaction Zn(s)+2H^(+)(aq)toZn^(2+)(aq)+H_(2)(g) addition of H_(2)SO_(4) to the cathode compartment will

Answer»

Lower the E and shift equilibrium to the left
lower the E and shift equilibrium to the right
increase the E and shift equilibrium to the right
Increase the E and shift equilibrium to the left

Solution :`E_(cell)=E_(cell)^(@)-(0.0591)/(2)"log"([ZN^(2+)]xxp_(H_(2)))/([H^(+)]^(2))`
On adding `H_(2)SO_(4),[H^(+)]` will increase, therefore `E_(cell)` will increase. The equilibrium `Zn+2H^(+)hArrZn^(2+)+H_(2)` will shift TOWARDS right on increasing the concentration of `H^(+)` IONS.
