Equilibrium constant Kp Flashcards
1
Q
How would you calculate partial pressure?
A
pp = mole fraction x total pressure
2
Q
How would you calculate mole fraction?
A
m.f. = moles of gas X in mixture / total moles in mixture
3
Q
How would you calculate Kp from a reversible reaction?
A
Kp = pp reactants / pp products
4
Q
What are the units for Kp?
A
kPa (depends via question)
5
Q
What is the effect of increasing temperature on Kp for an exothermic reaction?
A
Equilibrium shifts to the left
Partial pressure of products decreases
Kp decreases
6
Q
What is the effect of increasing the overall pressure on Kp in a reaction?
A
Pressure does not affect Kp
7
Q
How does a catalyst affect the value of Kp in a reaction?
A
Does not affect the equilibrium constant
