Question

Calculate the emf of the following cell at 25°C: Zn (s) | Zn²⁺ (0.1 M) || H⁺ (0.01 M) | H₂ (g) (1 bar), Pt (s) [Given: E°(Zn²⁺/Zn) = – 0.76 V, E°(H⁺/H₂) = 0.00 V, log 10 = 1]

State Kohlrausch law of independent migration of ions. Why does the conductivity of a solution decrease with dilution?

What should be the signs (positive/negative) for E°Cell and ΔG° for a spontaneous redox reaction occurring under standard conditions ?
