                    Which of the following expressions correctly represents the relationship between the average molar kinetic energy, \[\overline{KE}\], of CO and \[{{N}_{2}}\] molecules at the same temperature ?                                                              

    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 volumes of die gases are given        

    Correct Answer: C

    Solution :

                                                                                            KB = \[\frac{3}{2}\] RT (for one mole of a gas)                 The temperature is constant and kinetic energy is independent on molecular weights. So,                 \[{{\overline{KE}}_{CO}}={{\overline{KE}}_{{{N}_{2}}}}\]
