total pressure Flashcards
1
Q
what is meant by total pressure?
A
the sum of all partial pressures of each individual gas
2
Q
what is meant by a mole fraction?
A
the number of gas moles of an individual gas out of the total gas moles
3
Q
how can a partial pressure be found?
A
- use an ICE table to find moles
- calculate the mole fraction by dividing each by the total sum
- multiply by total pressure
4
Q
partial pressure equation
A
mole fraction x total pressure
5
Q
how is percentage of an individual gas in the mixture calculated?
A
- substitute into Kp equation to calculate partial pressures
- divide by total pressure
- x 100
