1. What are the cell reactions and their Ecell in the following systems? Are the reactions spontaneous? Assume that all systems are aqueous. (a) AgAgClK+,Cl(1M)Hg2Cl2Hg (b) PtCe3+(0.01M),Ce4+(0.1M),H2SO4(1M)Fe2+(0.01M),Fe3+(0.1M),HCl (1M) | Pt 2. Consider the cell in part (b) of Problem 1. What would the composition of the system be at the end of a galvanic discharge to an equilibrium condition? (Hint 1: Ecell=0V at equilibrium. Hint 2: Review equilibrium calculations from general chemistry or quantitative analysis.) What would the potential of each electrode be vs. NHE? vs. SCE? Take equal volumes on both sides. 3. The cell CdCd2+(0.00972M)Cd2+(0.00972M),CN(0.094M)Cd has a potential of 0.4127V at 25C. If the only significant reaction between Cd2+ and CN is the formation of Cd(CN)42, what is the equilibrium constant for the formation of Cd(CN)42
