Which of the following gases will have the highest rate of effusion at a given temperature?

cl2
he
o2
ne

He.

Explanation:

The molecular weights of the given gases are:

Cl₂ = 70.9 g/mol.

He = 2.0 g/mol.

O₂ = 32.0 g/mol.

Ne = 20.17 g/mol.

Since He has the smallest molecular mass, so it will have the highest rate of effusion.

He

Explanation:

Because it has the lowest molar mass out of all the choices.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
