    If X is the total number of collisions which a gas molecule register with others per unit time under particular conditions, then the collision frequency of the gas containing N molecules per unit volume is

    A)  X/N                                      

    B)  NX.

    C)  2 NX                                     

    D)  NX/2

    Correct Answer: D

    Solution :

                     Number of collisions of one molecule/unit time = X Number of collision of N molecules /unit time                                                                 = NX. As in one collision, two molecules are involved, collision frequency = NX/ 2
