Re: Concentration and Cell Potential
Concentration affects cell potential because of Le Chatelier's principle. An increase in concentration in one of the reactants causes the reaction to proceed right to make more products. This means a higher positive voltage being produced.

Re: Concentration and Cell Potential
You relate these two with the Nernst equation: E=E*-RT/nF x lnQ. (the * is a knot, I just can't find one on my keyboard)
So, if Q (concentration) increases then the term RT/nF x lnQ increases meaning you subtract a larger amount from E* and E is smaller.
So I believe concentration and cell potential have an inverse relationship.

Re: Concentration and Cell Potential
When either reactants increase or products decrease, cell potential increases. When either reactants decrease or products increase, cell potential decreases.

Re: Concentration and Cell Potential
Cell potential changes with the change in concentration: as the reactants increase and products decrease CP increases and as reactants decrease and products increase CP decreases.

Re: Concentration and Cell Potential
when reactants increase or products decrease, the reaction proceeds forward causing the cell potential to increase. And when the reactants decrease or products increase, the reaction proceeds to the left, causing the cell potential to decrease.
