Diffusion and Effusion Flashcards
Relation 1
Rate of effusion = 1/sqrt(molar mass)
Kelvin temperature is constant
Relation 2
Rate of effusion A / rate of effusion B = sqrt(molar mass B / molar mass A)
Same Kelvin temperature
Relation 3
Rate of effusion is directly proportional to average speed
Relation 4
Average speed gas A / average speed gas B = sqrt (molar mass B /molar mass A)
Relation 5
Effusion rate at T2/ effusion rate at T1 = sqrt (T2/T1)
Relation 6
Average speed at T2 / average speed at T1 = sqrt (T2/T1)
Relation 7
Average speed = sqrt (T/M)
Key Conclusions
Average speed of gas particles increases as:
-Tkelvin increases
-molar mass M decreases
KEaverage
KEaverage is directly proportional to Tkelvin
KEparticle
KEparticle = 1/2 mv^2
