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. (A) 460 L (B) 0.683 L (C) 1800 L (D) 1231.6 L

Tardigrade Admin · Accepted Answer

W=(I t E/96500) =(1000 × 9.65 × 35.5/96500)=3.55g Number of moles of chlorine obtained =(3.55/71)=0.05 PV=nRT 1.8× V=0.05× 0.082× 300 V=0.683 L

Q. How may litres of chlorine gas will be obtained by electrolysis of molten NaCl at 1.8 atm and $2 7^{\circ} C$ ? The electrolysis continued for 9.65 sec using 1000 amp current.

460 L

0.683 L

1800 L

1231.6 L

$W = \frac{I tE}{96500}$

$= \frac{1000 \times 9.65 \times 35.5}{96500} = 3.55 g$

Number of moles of chlorine obtained $= \frac{3.55}{71} = 0.05$

$P V = n RT$

$1.8 \times V = 0.05 \times 0.082 \times 300$

$V = 0.683$ L
