Reaction potential
the potential \[E = (– 0.337) – 0.0295 \log_{10} [Cu^{2+}]\] becomes more positive (the reaction has a greater tendency to take place) as the cupric ion concentration decreases. This, of course, is exactly what the Le Chatelier Principle predicts; the more dilute the product, the greater the extent of the reaction.When the concentrations in the two compartments are the opposite of the initial concentrations (i.e., 1.0 M Zn 2+ and 1.0 × 10 −6 M Cu 2+ ), Q = 1.0 × 10 6, and the cell potential will be reduced to 0.92 V. Figure : The Variation of E cell with Log Q for a Zn/Cu Cell. Initially, log Q < 0, and the voltage of the cell is greater than E° cell.
