    What is the ratio of kinetic energies of 3 g of hydrogen and 4 g of oxygen at T(K)?

    A)  12:1                                      

    B)  6:1

    C)  1:6                                        

    D)  24:1

    Correct Answer: A

    Solution :

                     We know that, \[K.E=\frac{3}{2}nRT\] \[\therefore \] \[\frac{{{(K.E)}_{{{H}_{2}}}}}{{{(K.E)}_{{{O}_{2}}}}}=\frac{{{n}_{{{H}_{2}}}}}{{{n}_{{{O}_{2}}}}}\]         (at T K)                 \[=\frac{3/2}{4/32}\] \[=12:1\]
