What is partial pressure?
The pressure an individual gas
exerts in a
mixture of gases
How do you calculate partial pressure?
mole fraction
x
total pressure
When writing Kp what is included?
Gasses
How do you calculate mole fraction?
Number of
moles
/ total number of
moles
of all
gasses
If Kp is small, what is favoured?
The reactants
Is Kp affected by pressure?
No
Is Kp affected by concentration?
No
Is Kp affected by changes in temperature?
Yes
How does Kp change if temperature is increased?
Equilibrium will shift to favour the
endothermic
direction.
If there are less products produced is Kp bigger or smaller?
Smaller
