PLEASE ANSWER PART D Heart pacemakers are often powered by lithium-silver chromate "button"batteries. The overall cell reaction is:2 Li(s) + Ag2CrO4(s) → Li2CrO4(s) + 2 Ag(s)(a) Lithium metal is the reactant at one of the electrodes of the battery. Is it the anodeor the cathode?(b) Choose the two half-reactions from a table of standard reduction potentials that mostclosely approximate the reaction that occur within the battery. What is the standardvoltage generated by a cell operating with these half-reactions?(c) The actual value is about +3.5 V for this pacemaker cell. How does that compare towhat you've shown me in (b)?(d) Calculate the voltage at body temperature.Standard reduction potentials are as below:Half-ReactionAgt (aq) + e Ag(s)AgBr(s) + ¢* * Ag(s) + Br"(aq)AgCl(s) + e Ag(s) + Cl(aq)Ag(CN)₂ (aq) +eAg(s) + 2 CN" (aq)AgaCrO₂ (s) + 2 e 2 Ag(s) + CrO2(aq)Agl(s) + e Ag(s) + (aq)Ag(S₂03)2(aq) +eAg(s) + 2S₂O3(aq)Al³+ (aq) + 3e Al(s)H₂AsO₂(aq) + 2H*(aq) + 2e H₂AsO₂(aq) + H₂O(1)Ba²+ (aq) + 2 e Ba(s)BIO+ (aq) + 2 H*(aq) + 3 e² → Bi(s) + H₂O(1)Br₂(1) +2 e 2 Br (aq)2 Bro, (aq) + 12 H*(aq) + 10 e Br₂(1) + 6H₂O(1)2 CO₂(g) + 2H(aq) + 2eH₂C₂O4(aq)Ca²+ (aq) + 2eCa(s)Cd(s)Ce³(aq)Cu²+ (aq) + 2eCu²+ (aq) + eCu (aq) +Cd²+ (aq) + 2eCe+ (aq) +Cl₂(g) + 2e- 2 C1 (aq)2 HCIO(aq) + 2H*(aq) + 2eCl₂(g) + 2 H₂O(1)CIO (aq) + H₂O(1) + 2e Cl(aq) + 2OH(aq)2 CIO, (aq) + 12 H(aq) + 10eCl₂(g) + 6H₂O(1)Co²+ (aq) + 2eCo(s)Cot(aq)Cost(aq) +ẽ+1.84 O₂(g) + 2H₂O(l) + 4e¯Cr³+ (aq) + 3eCr(s)-0.74 O₂(g) + 2H(aq) + 2e →Cr³+ (aq) + Cr²+ (aq)-0.41 O₂(g) + 2H*(aq) + 2eCr₂O₂(aq) + 14 H(aq) + 6e-2 Cr³+ (aq) +7H₂O() +1.33 Pb²+ (aq) + 2e Pb(s)CrO2(aq) + 4H₂O(1) + 3e--0.13 PbO₂(s) + HSO (aq) + 3H*(aq) + 2 eCr(OH),(s) + 5OH(aq)Cu(s)Cu* (aq)Cu(s)Cu(s) + (aq)Cul(s) +F₂(g) + 2e2F (aq)Fe²+ (aq) + 2eFe(s)Fe³+ (aq) + eFe²+ (aq)Fe(CN) (aq) + e Fe(CN),(aq)2H*(aq) + 2eE° (V)Half-Reaction+0.80 2 H₂O(1) + 2e H₂(g) + 2OH(aq)+0.10 HO₂ (aq) + H₂O(1) + 2e3OH(aq)+0.22 H₂O₂(aq) + 2H*(aq) + 2e-2H₂O(1)-0.31 Hg (aq) + 2e-2 Hg(1)+0.45 2 Hg (aq) + 2e Hg₂+ (aq)-0.15 Hg2+ (aq) + 2eHg(1)12₂(s) + 2e ► 21 (aq)-1.66 210,(aq) + 12 H(aq) + 10 e 1₂(s) + 6H₂O(1)+0.56 K*(aq) + eK(s)-2.90 Li*(aq) +eLi(s)+0.01H₂(g)+0.32 Mg (aq) + 2eMg(s)+1.07 Mn²(aq) + 2e"- Mn(s)+1.52 MnO₂(s) + 4H(aq) + 2e →→→Mn²+ (aq) + 2 H₂O(1)-0.49MnO, (aq) + 8H(aq) + SeMn² (aq) + 4H₂O(1)-2.87-0.40MnO₂ (aq) + 2H₂O(l) + 3eMnO₂(s) + 4 OH(aq)HNO₂(aq) + H(aq) + e NO(g) + H₂O(l)+1.61 N₂(g) + 4H₂O(1) + 4e4OH(aq) + N₂H₂(aq)+1.36 N₂(g) + 5H(aq) + 4e N₂H₂ (aq)NO(g) + 2H₂O(1)+1.63 NO₂ (aq) + 4H(aq) + 3e+0.89 Na (aq) + e- Na(s)+1.47-0.28Ni²+ (aq) + 2e → Ni(s)O₂(g) + 4H(aq) + 4e-2 H₂O(1)4 OH(aq)H₂O₂(aq)O₂(g) + H₂O(1)PbSO4(s) + 2 H₂O(1)+0.34+0.15 PIC12(aq) + 2e+0.52 S(s) + 2H(aq) + 2ePbSO4(s) + H(aq) + 2e Pb(s) + HSO₂ (aq)Pt(s) + 4 Cl(aq)H₂S(g)-0.19 H₂SO₂(aq) + 4H*(aq) + 4e¯S(s) + 3H₂O(1)H₂SO3(aq) + H₂O(1)+2.87 HSO (aq) + 3 H*(aq) + 2e-0.44 Sn²(aq) + 2e-Sn(s)+0.77 Sn (aq) + 2eSn²+ (aq)+0.36 VO₂ (aq) + 2H(aq) + e- VO²+ (aq) + H₂O(1)0.00 Zn²(aq) + 2e-Zn(s)E°(V)-0.83+0.88+1.78+0.79+0.92+0.85+0.54+1.20-2.92-3.05-2.37-1.18+1.23+1.51+0.59+1.00-1.16-0.23+0.96-2.71-0.28+1.23+0.40+0.68+2.07-0.13+1.69-0.36+0.73+0.14+0.45+0.17-0.14+0.15+1.00-0.76
