    A mixture of oxygen and hydrogen are filled in a vessel at a fixed temperature. The ratio of average kinetic energies of atoms of H2 and O2 is :

    A) 1 : 16                                     

    B) 1 : 8

    C) 1 : 12                                     

    D) 1 : 1

    Correct Answer: D

    Solution :

    We know that, kinetic energy \[E\propto T\] \[\therefore \]  \[\frac{{{E}_{1}}}{{{E}_{2}}}=\frac{{{T}_{1}}}{{{T}_{2}}}\]                 \[\frac{{{E}_{1}}}{{{E}_{2}}}=\frac{T}{T}\]              \[(\because {{T}_{1}}={{T}_{2}}=T)\]                 \[\frac{{{E}_{1}}}{{{E}_{2}}}=1\] Therefore, \[{{E}_{1}}:{{E}_{2}}=1:1\]
