Which equation represents the formation of ammonia

• N₂ + H₂ ₋> NH₃
• N + 3H ₋> NH₃
• N₂ + 3H₂ ₋> NH₃
• N₂ + 3H₂ ₋> 2NH₃

Hydrogen for the Haber process is made from

• Methane in natural gas
• Fractional distillation of air
• Fractional distillation of crude oil
• Electrolysis

Why aren't high pressures for the Haber process used in industry?

• Too expensive and dangerous
• Less ammonia is formed
• The reaction is too slow
• The catalyst is poisoned

What are the usual conditions of the Haber Process?

• 450'C, 550 atm, Iron Catalyst

• 100'C, 200 atm, Diamond Catalyst

• 450'C, 200 atm, Iron Catalyst

• -450'C, 250 atm, Iron Catalyst
