Question

At 298K the standard free energy of formation of H₂O (l) is –237.20 kJ/mole while that of its ionisation into H⁺ ion and hydroxyl ions is 80 kJ/mole, then the emf of the following cell at 298 K will be [Take Faraday constant F = 96500C]
H₂ (g , 1 bar) | H⁺ (1M) | | OH⁻ (1M) | O₂ (g, 1 bar)
(a) 0.40V
(b) 0.81V
(c) 1.23 V
(d) – 0.40 V

Answer 1

it is very easy

i know u can try it on ur own

just put the formulas and substitute the values

and kaboom ur answer is right there
