Question

Write word equation for the following molecular equation:

\[\ce{N2 + 3H2 ⇌[Fe - 450°C][200 atoms] 2NH3 + \triangle}\]

Word equation:
State why [+ Δ] indication is seen after NH₃.
State what 200 atmospheres – indicates.
State the function of Fe in the above reaction.

Answer 1

\[\ce{Nitrogen + Hydrogen ⇌[Fe - 450°C][200 atoms] Ammonia + \triangle}\]

1. + Δ at the end of the reaction represents heat evolved.
2. NH₄ (Ammonia) decomposes in the presence of 200 atmospheric pressure.
3. Fe(Iron) act as catalyst in the reaction.
