InterviewSolution

1.	At 298 K the standard free energy of formation of H2O(l) is −257.20 kJ/mole while that of its ionization into H+ ion and hydroxyl ions is 80.35 kJ/mole. Then the emf of the following cell at 298 K will be (take F=96500 C): H2(g, 1 bar)\|H+(1M)\|\|OH−(1M)\|O2(g, 1 bar)
Answer» At $298 K$ the standard free energy of formation of $H_{2} O (l)$ is $- 257.20 kJ/mole$ while that of its ionization into $H^{+}$ ion and hydroxyl ions is $80.35 kJ/mole$ . Then the emf of the following cell at $298 K$ will be $(take F = 96500 C)$ : $H_{2} (g, 1 bar) \| H^{+} (1 M) \| \| O H^{-} (1 M) \| O_{2} (g, 1 bar)$
