Question

9. How much faraday is required to liberate 5600 C. C oxygen
gas at NTP for electrolysis of dilute H2SO4
(a) 0.5 F
(b) 1F
(c) 1.5 F
, (d) 96500 F
​

Answer 1

5600c.c is nothing but 5600ml

1F of charge is required to liberate 1 gram equivalence of O2 gas at NTP.

1 gram equivalence of O2 gas = 5.6l = 5600ml

Thus, to liberate 5600cc of O2 gas, 1F of charge is required.

Hope it helps!!
