An HCl molecule has rotational, translational and vibrational motions. If the rms velocity of HCl molecules in its gaseous phase is \(\bar v\), m is its mass and \({k_B}\) is Boltzmann constant, then its temperature will be:

\(\frac{{m{{\bar v}^2}}}{{3{k_B}}}\)

\(\frac{{m{{\bar v}^2}}}{{6{k_B}}}\)

\(\frac{{m{{\bar v}^2}}}{{7{k_B}}}\)

\(\frac{{m{{\bar v}^2}}}{{5{k_B}}}\)
