Question

In Haber process 30 litres of dihydrogen and 30 litres of dinitrogen were taken for reaction which yielded only 50% of the expeced 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

$N_2+3H_2\rightleftharpoons 2N{H}_3$
30 30 0
30 - x 30 - 3x 2x

2x = 10; x = $\frac{10}{2}=5$
$N_2$ = 30 - 5 = 25 litre
$H_2$ = 30 - 3 $\times$ 5 = 15 litre
$N{H}_3$ = 2 $\times$ 5 = 10 litre
