AIPMT PRELIMS 2003 Chemistry Haber Process MCQ Question

Type: MCQ-numerical-Medium-Class 11

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 above 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 litres nitrogen, 30 litres hydrogen

D

20 litres ammonia, 25 litres nitrogen, 15 litres hydrogen

Correct Answer

Option B

Detailed Explanation

The balanced equation for the Haber process is N₂ + 3H₂ → 2NH₃. Initially, 30 litres of each reactant are taken. Since only 50% yield is achieved, 10 litres of ammonia are formed, leaving 25 litres of nitrogen and 15 litres of hydrogen unreacted.
