Identify the correct labels of A,BandCA, B and C in the following graph from the options given below:
Identify the correct labels of A, B and C in the following graph from the options given below: Root mean square speed (
Root mean square speed (Vrms);\left({V}_{rms}\right); most proable speed \left({V}_{mp}\right);Averagespeed(Vav)Average speed \left({V}_{av}\right)

Options

  1. AA−Vmp;B−Vrms;C−Vav\text{A} - {\text{V}}_{\text{mp}}; \text{B} - {\text{V}}_{\text{rms}}; \text{C} - {\text{V}}_{\text{av}}
  2. BA−Vav;B−Vrms;C−Vmp\text{A} - {\text{V}}_{\text{av}}; \text{B} - {\text{V}}_{\text{rms}}; \text{C} - {\text{V}}_{\text{mp}}
  3. CA−Vrms;B−Vmp;C−VavA - {\text{V}}_{\text{rms}}; \text{B} - {\text{V}}_{\text{mp}}; \text{C} - {\text{V}}_{\text{av}}
  4. DA−Vmp;B−Vav;C−Vrms\text{A} - {\text{V}}_{\text{mp}}; \text{B} - {\text{V}}_{\text{av}}; \text{C} - {\text{V}}_{\text{rms}}

Correct answer

D. A−Vmp;B−Vav;C−Vrms\text{A} - {\text{V}}_{\text{mp}}; \text{B} - {\text{V}}_{\text{av}}; \text{C} - {\text{V}}_{\text{rms}}

Step-by-step solution

Vmp(=2RTM)<Vav(=8RT\piM)<Vrms(=3RTM){\text{V}}_{\text{mp}}\left(\text{=}\sqrt{\dfrac{\text{2RT}}{\text{M}}}\right){\text{<V}}_{\text{av}}\left(\text{=}\sqrt{\dfrac{\text{8RT}}{\text{\pi M}}}\right){\text{<V}}_{\text{rms}}\left(\text{=}\sqrt{\dfrac{\text{3RT}}{\text{M}}}\right)
