Question

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

(a) 20 litres ammonia, 20 litres nitrogen, 20 litres hydrogen

(b) 10 litres ammonia, 25 litres nitrogen, 15 litres hydrogen

(c) 20 litres ammonia, 10 liters nitrogen, 30 litres hydrogen

(d) 20 litres ammonia, 25 litres nitrogen, 15 litres hydrogen

Answer 1

The correct option is (b) 10 L ammonia, 25 L nitrogen, 15 L hydrogen.

As only 50% of the expected product is formed,

hence only 10 L of NH₃ is formed.

Thus, for the production of 10 L of NH₃,5L of N₂ and 15 L of H₂ are used and composition of gaseous mixture under the aforesaid condition in the end is
