Haber Process

Haber process is the name we give to the industrial production of

• Sulfuric acid

• Ammonia

• Sodium hydroxide

• Nitric acid

Which equation represents the formation of ammonia?

• $N_2\ +\ H_2\ \ \leftrightarrow\ \ NH_3$
  

• $N+\ 3H\ \ \leftrightarrow\ \ NH_3$

• $N_2\ +\ 3H_2\ \ \leftrightarrow\ \ 2NH_3$

• $3N_2\ +\ H_2\ \ \leftrightarrow\ \ 2NH_3$

Nitrogen used in the Haber process is obtained from

• Fractional distillation of air

• Fractional distillation of crude oil

• Electrolysis of water

• Reduction of nitrogen oxide by carbon

Hydrogen used in the Haber process is obtained from

• Electrolysis of crude oil

• Cracking of crude oil

• Methane in natural gas

• Fractional distillation of air

Which metal is used as a catalyst in the Haber process?

• Sodium

• Silver

• Iron

• Copper

What is the optimal conditions for the Haber Process?

• $250\degree C$ and 450 atm
  

• $450\degree C$ and 250 atm

• $300\degree C$ and 200 atm

• $200\degree C$ and 300 atom

What is the effect of temperature on the yield of ammonia in the Haber process?

• The lower the temperature, the higher the yield

• The higher the temperature, the higher the yield

What is the effect of pressure on the yield of ammonia in the Haber process?

• The lower the pressure, the higher the yield

• The higher the pressure, the higher the yield

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

• The reaction will be too slow

• Very little ammonia will be produced

• The catalyst will be poisoned

• Expensive equipment will be needed

Why aren't very high temperatures used in the Haber process in the industry?

• The catalyst will be poisoned

• The reaction will be too slow

• The yield will be too high

• The yield will be too low
