A lithium battery is being developed. Its voltaic cell is constructed based on Li metal electrode and PbsO4 solid electrode. Their standard reduction potentials at 25 °C are given below. E°(Li* (aq) → Li (s)) = -3.040 Volt E°(PbSO4 (S) > Pb (s) + SO42 (aq) = - 0.356 Volt. Which of the following statements is true about this working (spontaneous) voltaic cell? a. The anode is PbsO4 (s) electrode. The standard cell potential of this voltaic cell is E°(cell) = 2.328 Volt O. PBSO4 (s) is a weaker oxidizing agent than Lit. To make a commercial product, the voltaic cell is adjusted to have [Lit] = 2.1 M and [SO42] = 3.5 M. The cell d. potential E under this condition should be less than the standard cell potential E°(cell). e. None of the above
