Question

IN the voltaic cell which is represented as Cu Cu +2 Fe +3 Fe. Write the half reactions that occur at each of the following electrodes. Refer to the table of standard reduction potential and calculate the E + for the following reaction for the reaction Calculate the deltaG + in joules Calculate the equilibrium constant, K e for the following reaction Calculate the emf for the following voltaic cell at 25 C. (you'll need the overall reaction and the nernst equation) How many grams of magnesium metal could be obtained by passing 10.0 amps through molten chlordie MgCl 2, for 4 hours? (1 faraday = 96,500 coulombs)

Explanation / Answer

1) 3x(Cu ------> Cu2+ + 2e-) = 3Cu ------> 3Cu+2 + 6e-

2x(Fe+3 + 3e- -------> Fe) = 2Fe+3 + 6e- -------> 2Fe

2) E
