During the electrolysis of molten sodium chloride, the time required to produce 0 . 10   mol of chlorine gas using a current of 3   amperes is

Step-by-step solution

For 1   mole of C l 2 ,   2 F electricity is required. ∴ For 0 . 1   mole of C l 2 ,   0.2   F electricity will be required. ∴ Q = I × t or, t = Q I = 0.2 × 96500 3 × 60 ≈ 110 minutes.
