Which of the following gases will have the- highest kinetic energy per mole at the same pressure & temperature ?
Correct answer: D. All the gases will have the same KE
- A. Chlorine
- B. Nitrogen
- C. Ethane
- D. All the gases will have the same KE
Explanation
For an ideal gas, the average kinetic energy per mole is proportional only to temperature, specifically 3RT/2, and does not depend on molecular identity or pressure. Therefore chlorine, nitrogen, and ethane have the same molar kinetic energy at the stated temperature.
