    The average kinetic energy of one molecule of an ideal gas at \[27{}^\circ \] and 1 atm pressure is

    A)  \[104\]

    B)  \[52153\]

    C)  \[Alkyne\xrightarrow[Lindlars\,\,catalyst]{{{H}_{2}}}A\xrightarrow{Ozonolysis}\underset{only}{\mathop{B}}\,\]

    D)  \[\xleftarrow[\Pr ocess]{Wac\ker }C{{H}_{2}}=C{{H}_{2}}\]

    Correct Answer: B

    Solution :

     Average kinetic energy per molecule \[=\frac{3}{2}KT\] or \[=\frac{3}{2}\frac{R}{{{N}_{0}}}T\] \[=\frac{3}{2}\times \frac{8.314}{6.023\times {{10}^{23}}}\times 300\] \[=6.21\times {{10}^{-21}}J{{K}^{-1}}molecul{{e}^{-1}}\]
