Question

Part A The Nernst equation is one of the most For the reaction 2Co3+ (aq) + 2C1_ (aq)-2Co2+ (aq) + Cl2(g). To calculate the cell potential at non- standard-state conditions, the equation is E. 0.483 v 3.80x10-2 M·Co2+-0.320 M what is the cell potential at 25°C if the concentrations are [Co3+ [CI-] = 4.00x10- M , and Ical-0.400 M? Express your answer with the appropriate units. View Avalilable Hint(s) E= Eo _ 2.sos a log10Q where E is the potential in volts, E is the standard potential in volts, R is the gas constant, T is the temperature in kelvins, n is the number of moles of electrons transferred, F is the Faraday constant, and Q is the reaction quotient. At standard temperature, 25 ° Cor 298 K, the equation has the form 0.403 0.0592 logQ Submit|P The reaction quotient has the usual form productsl Feactants x Incorrect; Try Again; no points deducted 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. Provide Feedback Next >
