Answer
(a) Nitrogen reacts with hydrogen under specific conditions liberating ammonia
N2 + 3H2 ⇌ 2NH3 + Δ
Conditions :
Temperature : 450-500°C [Optimum temperature]
Pressure : 200 to 900 atmospheres [Optimum pressure]
Catalyst : Finely divided iron [Fe]
(b) Moist hydrogen gas combines with chlorine in presence of diffused sunlight.
H2 + Cl2 ⟶ 2HCl [g]
Conditions — Diffused Sunlight, reaction is explosive in direct sunlight. Moisture acts as a catalyst.
