(a)Calculate the time it would take to form 515.0 g of PbO2 if you recharge a lead-acid storage battery with a constant current of 28.2 Amps. Pb(s) + PbO2(s) + 2 SO4
2-(aq) + 4 H3O+(aq) 􀃆 2 PbSO4(s) + 6H2O (l)
(b) Calculate the standard free energy change, Î"Go , and the equilibrium constant, K, for the reaction as written in part (a) at 25° C. Is the reaction as written spontaneous?
