Question

5. When nitrogen and hydrogen gases (in 1:3 ratio) are heated at high temperature and
high pressure under the presence of iron (as catalyst), a gaseous product ammonia
is formed. If the gaseous product so formed is not immediately cooled, the change
reverses. Will you call this a chemical change? Give reasons for your answer.​

Answer 1

Answer:

It is a chemical combination reaction. The process converts atmospheric nitrogen (N2) to ammonia (NH3) by a reaction with hydrogen (H2) using a metal catalyst under high temperatures and pressures. This process is known as Haber's Process.

Option (A) is correct.
