Average velocity depends on the molar mass of the molecule, and it is highest for [tex]H_{2}[/tex]. Average kinetic energy is the same for all molecules, at a constant temperature, because it does not depend on molar mass.

What is Kinetic energy?

An object's kinetic energy is the energy it has as a result of motion. It is described as the effort required to move a mass-based body from rest to the indicated velocity.

What is Molar mass?

The sum of all the atoms' individual masses in grams that make up a mole of a specific molecule is known as the molar mass, sometimes referred to as molecular weight. Grams per mole is the unit of measurement.

Hence, average velocity depends on the molar mass of the molecule, and it is highest for [tex]H_{2}[/tex].
