Consider the cell at 350 K based on the reaction Cl2(g)+Zn(s)⇌2 Cl−(aq)+Zn2+(aq)\mathrm{Cl}_2(g) + \mathrm{Zn}(s) \rightleftharpoons 2\,\mathrm{Cl}^-(aq) + \mathrm{Zn}^{2+}(aq) Relevant standard reduction potentials are E∘(Cl2/Cl−)=+1.36 VE^{\circ}(\mathrm{Cl}_2/\mathrm{Cl}^-) = +1.36\,\text{V} and E∘(Zn2+/Zn)=−0.76 VE^{\circ}(\mathrm{Zn}^{2+}/\mathrm{Zn}) = -0.76\,\text{V}. The system contains Cl−(aq)\mathrm{Cl}^-(aq) at 0.30 M0.30\,\text{M}, Zn2+(aq)\mathrm{Zn}^{2+}(aq) at 0.050 M0.050\,\text{M}, and Cl2(g)\mathrm{Cl}_2(g) at 0.80 atm0.80\,\text{atm}. What is the cell potential under these conditions? (a) 2.28 V2.28\,\text{V} (b) 2.04 V2.04\,\text{V} (c) 2.20 V2.20\,\text{V} (d) 2.19 V2.19\,\text{V}
