Harber process and equilibrium, paper 1 Flashcards
1
Q
What’s the harder process word equation:
A
Ammonia + oxygen —> nitric acid + water
Then
Ammonia + nitric acid —> ammonia nitrate
Or
Ammonia + sulphuric acid —> ammonia sulphate.
2
Q
The harber process symbol equation:
A
NH3 + O2 —> HNO3 + H2O Then NH3 + HNO3 —> NH4NO3 Or 2NH3 + H2SO4 —> 2(NH4)SO4
3
Q
What factors help to shift the equilibria?
A
- temperature
- pressure
- concentration.
4
Q
What is a dynamic equilibrium?
A
Where the forwards reaction is the same rate as the backwards one.
5
Q
When you increase temperature
A
You shift the equilibrium to the ENDOTHERMIC direction.
6
Q
When you increase the pressure the equilibrium:
A
Shits to the EXOTHERMIC direction.
7
Q
With increasing Concentration the equilibrium…
A
Shifts equilibrium towards the products.
