The Haber Process Flashcards
1
Q
What is the balanced symbol equation for the Haber process?
A
N2(g) + 3H2(g) ⇌ 2NH3(g)
2
Q
What is the energy change for the Haber process?
A
-93 kJ/mol
3
Q
Is the Haber process endothermic or exothermic?
A
exothermic
4
Q
What are the conditions for the Haber process?
A
- 200 atmospheres pressure
- 450 C
- Iron catalyst
5
Q
Why is a higher pressure not used to increase the rate of reaction?
A
it is hazardous and expensive to choose a hgher pressure and the higher equilibruim yield would not justify the additional costs
6
Q
How is the temperature for the Haber process chosen?
A
It is low enough to achieve a reasonable equilibrium yield but high enough to achieve a reasonable rate of reaction and the iron catalyst works more efficiently above 400C
