10C - Dalton's Law Flashcards
1
Q
Def: What is Dalton’s law of partial pressures?
A
States the total pressure of a gas mixture is the sum of partial pressures.
Ptotal = Sum(Pindividual)
P = P1 + … + Pn
2
Q
Def: What is Dalton’s law of partial pressures for ideal gases.
A
P = (n1 + … + n2)RT/V
3
Q
Def: What is a mole fraction?
A
The partial pressure of a gas can be expressed as the mole fraction times the total pressure.
PA = XA * Ptotal
4
Q
Def: What is the relationship between the properties of a gas solution and its individual components, and the mole fraction.
A
Pa/Ptotal = na/ntotal = Xa
