- Cooling to liquefy
- Heating to evaporate
-
What happens to the remaining nitrogen and hydrogen?
- They are recycled
- They are burned
- They are dissolved
- They are discarded
-
In the Haber process, nitrogen and hydrogen react in what molar ratio?
- 1 to 1
- 2 to 1
- 3 to 1
- 1 nitrogen to 3 hydrogen
-
What happens during a reversible reaction like the Haber process?
- Products form reactants
- All atoms are destroyed
- Only reactants form
- Energy drops to zero
-
Why are unreacted gases recycled in the Haber process?
- To remove the catalyst
- To cool the reactor
- To produce more heat
- To reuse raw materials
-
What is the purpose of the iron catalyst in the Haber process?
- Increases yield
- Increases rate
- Lowers pressure
- Lowers temperature
-
Which physical change happens to ammonia upon cooling in the Haber process?
- Liquefies
- Evaporates
- Sublimes
- Solidifies
-
What are the two raw materials used in the Haber process?
- Carbon and nitrogen
- Hydrogen and oxygen
- Oxygen and nitrogen
- Nitrogen and hydrogen
-
Which catalyst is used in the Haber process?
- Copper
- Cobalt
- Nickel
- Iron
-
Why is an extremely high pressure avoided in the industrial Haber process?
- Stops the reaction
- Lowers the yield
- Destroys the catalyst
- High energy costs
-
What happens to forward and reverse reaction rates at dynamic equilibrium?
- Reverse is faster
