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

The correct option is C 10 litres ammonia, 25 litres nitrogen, 15 litres hydrogen

It is given that only 50% of the expexted product is formed.
Hence, only 10 litres of $N{H}_3$ is formes i.e., $N_2$ used = 5 litres $\Rightarrow N_2$ left $=30-5=25$ litres
$H_2$ used $=15$ litres $\Rightarrow H_2$ left$=30-15=15$ litres
