How may litres of chlorine gas will be obtained by electrolysis of molten NaCl at 1.8 atm and $27 ° C$ ? The electrolysis continued for 9.65 sec using 1000 amp current.

Options:

Answer:

Solution:

$W = \frac{I t E}{96500}$
$= \frac{1000 \times 9.65 \times 35.5}{96500} = 3.55 g$
Number of moles of chlorine obtained $= \frac{3.55}{71} = 0.05$
$P V = n R T$
$1.8 \times V = 0.05 \times 0.082 \times 300$
$V = 0.683$ L
