Question

Rank these gases in order of decreasing effusion rates: F2, HCI, and Ar

Answer 1

higher molecular mass -> slower diffusion

Answer 2

how do i know how to do it ?

Answer 3

find the molecular masses of each with the aid of a periodic table

Answer 4

a. Ar>F2>HCI
b.HCI>F2>Ar
c.Ar>HCI>F2
d.F2>HCI>Ar

so its D ?

Answer 5

there are 2 F in F2

Answer 6

so it would be A or B?

Answer 7

yes one of those

Answer 8

order of decreasing effusion rates = order of increasing molecular mass

Answer 9

the answer is B ?

Answer 10

yep
