Formulas and Key Relations

2) Nernst Equation and Thermodynamics

E_(M^n+/M) = E_(M^n+/M)^0 - (RT/nF) ln(1/[M^n+])

E_(cell) = E_(cell)^0 - (RT/nF) ln Q

E^0_(cell) = (2.303RT/nF) log Kc

ΔrG = -nFE_(cell)

3) Conductance, Resistivity, Conductivity, Molar Conductivity

R = ρ l / A

G = 1/R = A/(ρl) = κA/l

G* = l/A = Rκ

Λm = κ/c

4) Variation of Molar Conductivity and Kohlrausch Law

Λm = Λm° - A c1/2

Λm° = ν+ λ+° + ν- λ-°

α = Λm / Λm°

Ka = cα2/(1-α)

Ka = cΛm2 / [Λm°(Λm° - Λm)]
