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

  • question_answer Which of the following expressions correctly represents the relationship between the average molar kinetic energy, \[\overline{K.E.}\], of CO and \[{{N}_{2}}\] molecules at the same temperature [CBSE PMT 2000]

    A)                 \[{{\overline{KE}}_{CO}}={{\overline{KE}}_{{{N}_{2}}}}\]

    B)                 \[{{\overline{KE}}_{CO}}>{{\overline{KE}}_{{{N}_{2}}}}\]

    C)                 \[{{\overline{KE}}_{CO}}<{{\overline{KE}}_{{{N}_{2}}}}\]

    D)                 Cannot be predicted unless the volumes of the gases are given

    Correct Answer: A

    Solution :

                    For same temp. kinetic energies would be equal for all molecules, what ever their molecular weights will be, it doesn't matter.
