Kp Flashcards
What does homogeneous mean?
All reactants and products are in the same phase
How do you calculate partial pressure?
Mol fraction x total pressure
What is the generic formula for Kp
p(reactants)
What can you not do with Kp
Put square brackets
How do you calculate mol fractions
Mol of x/ total mol
Kp is only affected by…
Temperature change
When Kp is less than 1, equilibrium is
To the left
When Kp is more than 1, equilibrium is
To the right
When Kp is exactly 1, equilibrium is
In the middle
How does a decrease in temperature affect Kp?
Increases
How does an increase in pressure affect Kp
It doesn’t
Explain what effect the increase of temperature has on Kp
🔼H= -467
•Kp will decrease
•forwards reaction is exothermic
•equilibrium will shift to the left to oppose increase in temperature
Why can you not put square brackets in Kp
[X] means concentration
