CI 2 Flashcards
1
Q
How is nitric acid produced?
A
- Ammonia is oxidised
- Absorption of the resulting nitrogen oxides
2
Q
What does increasing the pressure do to a reaction?
A
Moves the equilibrium to the side of the equation with fewer gas molecules
3
Q
What happens to the equilibrium constant (Kc) when a reaction is compressed?
A
Kc increases
4
Q
What happens to a reaction when temperature is increased?
A
Kc will favour the endothermic reaction as there is more energy to take
5
Q
When is the composition and equilibrium constant changed in a reaction?
A
When reaction temperature is changed
6
Q
What happens to Kc and composition when concentration or pressure is changed?
A
Composition may change but Kc is unchanged
7
Q
What happens to composition and Kc when a catalyst is added to a reaction?
A
Nothing
8
Q
When is rate constant (K) constant?
A
When temperature is constant
