|
Term
| The Effect of Concentration on Cell Potential |
|
Definition
When Q < 1 and thus [reactant] > [product], lnQ < 0, so Ecell > E0cell
When Q = 1 and thus [reactant] = [product], lnQ = 0, so Ecell = E0cell
When Q >1 and thus [reactant] < [product], lnQ > 0, so Ecell < E0cell
Ecell = E0cell - .0592/n *log Q |
