Below regarding an electrochemical cell in an automotive lead-acid battery. the cell's anode is made of lead and the cathode is made of lead(iv) oxide. both are submerged in 4.30 m sulfuric acid. the half-reactions are: pbo_2(s) + 3h^+ (aq) + hso_4^- (aq) + 2e^- rightarrow pbso_4(s) + 2h_2o(l) e degree = 1.685 v pbso_4(s) + h^+(aq) + 2e^- rightarrow pb(s) + hso_4^- (aq) e degree = -0.356 v (a) calculate the value of e degree. (b) determine the initial value of e_cell. assume that the first ionization of h_2so_4 is complete and that [h^+] almostequalto [hso_4^-]. (c) find e_cell when the h^+ concentration has dropped by 76.00%. again, assume [h^+] almostequalto [hso_4^-].
