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∘−(0.0591n)logQ where E∘ 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 Mfor all solutions and 1.00 atm for all gases. The Nernst equation allows for...
