3.1.6 - Equilibria Flashcards
1
Q
ICE acronym
A
Initial moles
Change in moles
Equilibrium moles
2
Q
How does temperature affect Kc?
A
If equilibrium shifts right, Kc increases
If equilibrium shifts left, Kc decreases
3
Q
Kc expression
A
[Products]^moles/[reactants]^moles
4
Q
Kc calculation
A
Find concentrations, plug into Kc expression
5
Q
What is the only variable which has an effect on Kc?
A
Temperature
6
Q
What does a increase in temperature favour?
A
The endothermic recaction direction
7
Q
If the container has increased in volume, what happens to the pressure and equilibium?
A
- Pressure decreases
- Equilbrium shifts to side with more moles
8
Q
How do you calculate partial pressures?
A
Mole fraction x total pressure
