Question

Constants Periodic Table РапA The Nernst equation is the one of the most important equations in electrochemistry. At standard temperature, 25 °C or 298 K, the equation has the form E=E° – (0.0591 ) logQ For the reaction 2CO3+ (aq) + 2Cl(aq) +2Co2+ (aq) + C1, (g). E=0.71 V what is the cell potential at 25°C if the concentrations are Co3] =0.728 M, Co2+] = 0.143 M, and [Cl] =0.116 M and the pressure of Cl2 is Pci, = 5.60 atm? Express your answer with the appropriate units. where Eº is the standard reduction potential for the reaction in volts and Q is the reaction quotient. The reaction quotient has the usual form View Available Hint(s) Q- products/ [reactants 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.
