Name: 2. The standart electromotive force of the cell Cd(Hg)(k) | CdSO4.8/3H2O | CdSO4(aq) | Hg2SO4(k) | Hg(s) is given below depending on temperature in °C: E/V= 1.01845-4.05x10^-5 (t-20)-9.5x10^-7(t-20)^2 (a) What are the cell reactions? (b) What are the values of E°, ?rG°, ?rS°, ?rH° and K at 25 °C? (c) Which is the negative electrode (anode (L) or cathode (R)) on open curcuit when the activities of all compounds are unity.
