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
- A460 L
- B0.683 L
- C1800 L
- D1231.6 L
Correct answer
B. 0.683 L
Step-by-step solution
W = I t E 96500 = 1000 × 9.65 × 35.5 96500 = 3.55 g Number of moles of chlorine obtained = 3.55 71 = 0.05 P V = n R T 1.8 × V = 0.05 × 0.082 × 300 V = 0.683 L
