Question

The electrolysis of acetate solution produces ethane according to reaction:
$2 C H_{3} C O O^{-} ⟶ C_{2} H_{6} (g) + 2 C O_{2} (g) + 2 e^{-}$
The current efficiency of the process is $80 %$ . What volume of gases would be produced at $27^{\circ} C$ and $740 t o r r$ , if the current of $0.5 a m p$ is passed through the solution of $96.45$ min?

Solution

The correct option is D $0.91 L$
From reaction, it can be seen that 2 mole of the electron produces 3 mol of gases.

Here, charge $= 0.5 \times 0.8 \times 96.45 \times 60 = 2314.8$ coulomb.

So volume of gases produces $1.5 \times 2314.8 \times 22.4 / 96500 = 0.815 L$ .

So volume of gases at 740 torr is $\frac{V_{2}}{V_{1}} = \frac{P_{1}}{P_{2}}$ at constant temperature.

So $V_{2} = 0.815 \times \frac{760}{740} = 0.84 L$
