Question

Give the balanced reaction for the manufacture of the ammonia gas.

• A. $3N_2+3H_2\to 6{NH}_3$
• B. $N_2+3H_2\to 2{NH}_3$
• C. $N_2+3H_2\to {NH}_3$
• D. $N_2+6H_2\to 4{NH}_3$

Answer 1

The correct option is B $N_2+3H_2\to 2{NH}_3$

$N_2+3H_2\to 2{NH}_3$
In the manufacture of ammonia process employed is Haber-Bosch which occurs in the presence of catalyst at high temperature and high pressure.
