The Nernst equation is the one of the most important equations in electrochemistry. At standard temperature, 25 âC or 298 K, the equation has the form E=Eââ(0.0591n)logQ where Eâ 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. Using the reaction and the Eâ given below 2Co^3+(aq)+2Cl^â(aq)â2Co^2+(aq)+Cl2(g) Eâ=0.46 V what is the cell potential at 25 âC if the concentrations are [Co^3+]= 0.766 M , [Co^2+]= 0.649 M , and [Cl^â]= 0.145 M and the pressure of Cl2 is PCl2= 2.10 atm ?
