$\left(a\right)$ Represent $U_{\mathrm{mps}},{\mathrm{U}}_{\text{avg }}$and ${\mathrm{U}}_{\mathrm{rms}}$ on a curve plotted between fraction of molecules versus velocity using Maxwell equation for molecular collisions.

$\left(b\right)$ Are the no. of molecules moving within a particular range of velocity same for $\mathrm{NO}$ and ${\mathrm{C}}_2{\mathrm{H}}_6$ at same temperature?
