In a cell that utilizes the reaction
Zn(s) + 2H+(aq) → Zn2+(aq) + H2(g)
addition of H2SO4 to cathode compartment, will
(a) lower the E and shift equilibrium to the left
(b) lower the E and shift the equilibrium to the right
(c) increase the E and shift the equilibrium to the right
(d) increase the E and shift the equilibrium to the left.
