Which molecules of the following gases will
have the greatest average kinetic energy?
1. N2 at 1 atm and 298 K
2. CO2 at 1 atm and 298 K
3. H2 at 0.5 atm and 298 K
4. He at 0.1 atm and 298 K
5. All of the molecules have the same kinetic
energy

All the molecules have the same average kinetic energy as average kinetic energy is directly proportional to the absolute temperature. So, the correct option is 5.

What is average kinetic energy?

The average kinetic energy (K) is equal to one-half of the mass (m) of each gas molecule times the root mean square speed (Vrms) squared.

We know that the average kinetic energy is directly proportional to the absolute temperature.

All of the molecules have the same kinetic energy since the temperature is kept constant at 298 K.

Therefore, All the molecules have the same average kinetic energy as average kinetic energy is directly proportional to the absolute temperature.
