Formulas and Key Relations

1 Conductivity of Electrolytic Solutions

Resistance (R) is inversely proportional to conductance (C)

C = 1/R

Resistivity (ρ) depends on the nature of the electrolyte and is defined as R = ρ(l/A)

4 Thermodynamics and Nernst Equation

At equilibrium (when Ecell = 0): ΔG° = -nFEcell° = -RT ln(Keq) = 0, so Keq = 1 doesn't mean K=1
