Question

In Haber process 30 litres of dihydrogen and 30 litres of dinitrogen were taken for reaction which yielded only 50% of the expected product. What will be the composition of gaseous mixture under the aforesaid condition in the end.

• A. 20 litres ammonia, 25 litres nitrogen, 15 litres hydrogen
• B. 20 litres ammonia, 20 litres nitrogen, 20 litres hydrogen
• C. 10 litres ammonia, 25 litres nitrogen, 15 litres hydrogen
• D. 20 litres ammonia, 10 litres nitrogen, 30 litres hydrogen

Answer 1

Answer: (C)

10 litres ammonia, 25 litres nitrogen, 15 litres hydrogen

Answer 2

⇌ $2 \mathrm { NH } _ { 3 }$

30 30 0

30-x 30-3x 2x

2x = 10 ; x =$\frac { 10 } { 2 } = 5$

$N _ { 2 } = 30 - 5 = 25$litre
