Passage / Comprehension

Adiponitrile (C₆H₈N₂), a key intermedate in the manfacture of nylon, is made industrially by an electrolysis process that reduces acrylonitrile and oxidizes water.

How many litres of $O_{2}$ at $1 atm, 27 3^{\circ} C$ are produced as a by product by passing 9.65 amp current till 10 hour. (Given $1 F = 96500 C, R = 0.0821 L - atm mol^{- 1} K^{- 1}$ )

Options:

Answer:

Solution:

Total charge $= \frac{10 \times 3600 \times 9.65}{96500} = 3.6 F$

$2 H_{2} O \to O_{2} + 4 H^{+} + 4 e^{-}$

$(n_{O_{2}}) = \frac{3.6}{4} = 0.9$

$V_{O_{2}} = \frac{0.9 \times 2 \times 273 \times 0.0821}{1} = 40.32 L$
