JEE Main & Advanced Chemistry States of Matter Question Bank Kinetic molecular theory of gases and Molecular collisions

  • question_answer At STP, 0.50 mol \[{{H}_{2}}\] gas and 1.0 mol He gas [CBSE PMT 1993, 2000]

    A)                 Have equal average kinetic energies

    B)                 Have equal molecular speeds    

    C)                 Occupy equal volumes

    D)                 Have equal effusion rates

    Correct Answer: A

    Solution :

                    For same temperature kinetic energies of \[{{H}_{2}}\And He\] molecules will be same because kinetic energy depends only on temperature.
