Electrochemsitry Equations
Cards in this deck (7)
- 1What equation links time, current and charge?Q = It
- 2How do you calculate Ecell?Ecell = Ered - Eox
Ecell = E(RHS) - E(LHS)
Ecell = E(cathode) - E(anode) - 3What equation links Ecell to Gibbs free energy for cells and half-cells?ΔG = -zF Ecell
(don't forget the minus sign) - 4What links Ecell/Ehalf-cell to the equilibrium constant?E = (RT / zF) lnK
- 5Define the Nernst EquationE = E(standard) - (RT / zF) lnQ
- 6How do we define the reaction quotient?Q = [Πa(products)^vp] / [Πa(reactants)^vr]
- 7How do you calculate the activity of a solution?a = γ ([x] / 1mol dm^-3)
