WebFeb 3, 2016 · Multiplying the charge on the electron by Avogadro’s number gives us the charge on 1 mol of electrons, which is called the faraday (F), named after the English physicist and chemist Michael Faraday (1791–1867): F = (1.60218 × 10 − 19 C)(6.02214 × 1023J 1 mol e −) = 9.64833212 × 104 C/mol e − ≃ 96, 485J / (V ⋅ mole −) WebNow let's repeat the same exercise with a fairly big positive value of ΔG° = +60.0 kJ mol -1. And we will keep the same temperature as before - 373 K. ΔG° = -RT ln K. +60000 = -8.314 x 373 x ln K. This gives ln K = -19.35.
