Thermodynamics Flashcards
1
Q
What is SATP?
A
T = 298K, p= 1.00x10^5
2
Q
What is the combined gas law?
A
P1V1 / T1 = P2V2 / T2, temp must be in kelvin and the units of volume and pressure must be the same for both gases
3
Q
What is Dalton’s law?
A
P (total) = Pa + Pb, the total pressure = sum of partial pressures
4
Q
How do you calculate a mole fraction?
A
nA/ nTotal
5
Q
How do you calculate partial pressure?
A
Mole fraction x total pressure
6
Q
What is the kinetic model?
A
- Gas molecules move constantly and at random
- Size of molecule is negligible compared with distance between them
- Molecules don’t interact other than bouncing off each other
7
Q
What is the equation for molecular speed?
A
[(S1^2 + S2^2 + S3^3 … SN^2)/N]^1/2
