Kp Flashcards
1
Q
Define partial pressure
A
Gas exerted by each individual gas from mixture
2
Q
What is the total pressure of a gas?
A
Sum of partial pressure of each individual gas
3
Q
How do you work out the partial pressure?
A
- Mole fraction of gas = no. moles of gas / total no. moles of gas in mixture
- PP = mole fraction of gasx total pressure
4
Q
What is the expression of Kp?
Unit
A
Kp = (pProducts) / (pReactants)
kPa
5
Q
Does changing the pressure affect Kp?
A
- No
- Equil shifts to oppose change
6
Q
Does adding a catalyst affect Kp?
A
- No
- Equilibirum is reached faster
7
Q
Does changing the temperature affect Kp?
A
Yes
