Quick Recap — Cell Potential, Nernst & Faraday

• $E^\circ_{cell}=E^\circ_{cathode}-E^\circ_{anode}$; Nernst (298 K): $E=E^\circ-\dfrac{0.059}{n}\log Q$.
• At equilibrium $E=0$: $E^\circ=\dfrac{0.059}{n}\log K$; $\Delta G^\circ=-nFE^\circ$.
• Faraday: $m=\dfrac{M}{nF}It$; $1$ mol electrons $=96500$ C.
• Molar conductivity: $\Lambda_m=\dfrac{\kappa\times1000}{C}$ (κ in S/cm, C in mol/L).
