    At very high temperatures vibrational degrees also becomes active. At such temperatures an ideal diatomic gas has a molar specific heat at constant pressure, \[{{C}_{p}}\] is

    A) 3R/2

    B) 5R/2  

    C) 6R/2

    D) 9R/2

    Correct Answer: D

    Solution :

    [d] At high temperature for diatomic gas\[f=7\] \[{{C}_{p}}=\frac{fR}{2}+R=\frac{9R}{2}\]
