Of the following gases, will have the greatest rate of effusion at a given temperature. a) nh3b) ch4c) ard) hbre) hcl

CH₄

Explanation:

According to Graham's law, the rate of effusion of a gas (r) is inversely proportional to the square root of its molar mass (M).

Let's consider the following gases and their molar masses.

A) NH₃    17.03 g/mol

B) CH₄    16.04 g/mol

C) Ar       39.95 g/mol

D) HBr    80.91 g/mol

E) HCl     36.46 g/mol

Of these gases, CH₄ will have the greatest rate of effusion at a given temperature because it has the lowest molar mass.

you need to stop taking that class

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
