Which among the following is produced using ‘Haber Process’?

Correct option is A

✅ (a) Ammonia: • Haber process synthesizes ammonia (NH₃) from nitrogen and hydrogen gases. • Reaction: N₂ + 3H₂ ⇌ 2NH₃ (under high pressure and temperature with Fe catalyst). • Widely used for producing nitrogen fertilizers.
❌ (b) Carbon dioxide: • A by-product in several processes but not the goal of Haber process.
❌ (c) Sulphur dioxide: • Produced via combustion of sulfur or sulfide ores (used in Contact Process, not Haber).
❌ (d) Ozone: • Formed by photochemical reactions or electrical discharge in oxygen, unrelated to Haber.
