Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25°C. (The equation is balanced.)
1.
3Cl2(g) + 2Fe(s) --> 6Cl-(aq) + 2Fe3+(aq)
Cl2(g)+2e- -->2Cl-(aq) E*= +1.36 V
Fe3+(aq)+3e- -->Fe(s) E*= -0.04 V
2.
Pb(s) + Br2(l) --> Pb2+(aq) + 2Br-(aq)
Pb2+(aq)+2e- -->Pb(s) E*= -0.13 V
Br2(l)+2e- --> 2Br-(aq) E*= +1.07 V
3.
Sn(s) + 2Ag+(aq) --> Sn2+(aq) + 2Ag(s)
Sn2+(aq)+2e- --> Sn(s) E*= -0.14 V
Ag+(aq)+e- --> Ag(s) E*= +0.80 V

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
