Chem

The Nernst equation is the one of the most important equations in electrochemistry. At standard temperature, 25 degree C or 298 K, the equation has the form E = E0- (0.0591/n)IogQ where E degree is the standard reduction potential for the reaction in volts and Q is the reaction quotient. The reaction quotient has the usual form Q = [products]x/[reactants] y A table of standard reduction potentials gives the voltage at standard conditions, 1.00 M for all solutions and 1.00 atm for all gases. The Nernst equation allows for the calculation of the cell potential E at other conditions of concentration and pressure. Part A For the reaction 2Co3+(aq) + 2Cl-(aq) rightarrow 2Co2+(aq) + Cl2(g). E degree = 0.71 V what is the cell potential at 25 degree C if the concentrations are [Co3*] = 0.456 M , [Co2+] = 3.20*10_2M, and [Cl-] = 0.697 M and the pressure of CI2 is Pcl2 = 8.90atm ? Express your answer with the appropriate units. Consider the following galvanic cell: What is the change in the cell voltage on decreasing the ion concentrations in the anode compartment by a factor of 100? Express your answer using two significant figures.
