Question 1
Which important industrial chemical is produced using the Haber process?
- AAmmonia
- BEthanol
- CCalcium carbonate
- DCopper sulfate
Show answerHide answer
Answer: A
The Haber process is used industrially to produce ammonia.
Question 2
Which equilibrium represents the formation of ammonia in the Haber process?
- AN2 + 3H2 ⇌ 2NH3
- BN2 + H2 ⇌ NH3
- C2N2 + H2 ⇌ 2NH3
- DNH3 ⇌ N2 + H2
Show answerHide answer
Answer: A
The Haber process uses nitrogen and hydrogen to form ammonia according to N2 + 3H2 ⇌ 2NH3.
Question 3
Why is the Haber process considered a reversible equilibrium process?
- AAmmonia can decompose back into nitrogen and hydrogen
- BAmmonia cannot react again
- CNitrogen is a liquid
- DHydrogen is removed permanently
Show answerHide answer
Answer: A
Ammonia can undergo the reverse reaction to regenerate nitrogen and hydrogen.
Question 4
What happens to ammonia formation when pressure is increased in the Haber process?
- AIt decreases
- BIt increases
- CIt stops
- DIt becomes impossible
Show answerHide answer
Answer: B
Increasing pressure favors the side with fewer gas moles and therefore favors ammonia formation.
Question 5
Why does increased pressure favor ammonia formation?
- AThe product side has fewer moles of gas
- BThe reactant side has fewer moles of gas
- CAmmonia is a solid
- DHydrogen becomes a liquid
Show answerHide answer
Answer: A
N2 and 3H2 give 4 moles of gas while 2NH3 gives 2 moles.
