Question:

Points I, II and III in the following plot respectively correspond to

$\left(\mathrm{V}_{\mathrm{mp}}\right.$ : most probable velocity)

  1. $\mathrm{V}_{\mathrm{mp}}$ of $\mathrm{N}_{2}(300 \mathrm{~K}) ; \mathrm{V}_{\mathrm{mp}}$ of $\mathrm{H}_{2}(300 \mathrm{~K})$;

    $\mathrm{V}_{\mathrm{mn}}$ of $\mathrm{O}_{2}(400 \mathrm{~K})$

  2. $\mathrm{V}_{\mathrm{mp}}$ of $\mathrm{H}_{2}(300 \mathrm{~K}) ; \mathrm{V}_{\mathrm{mp}}$ of $\mathrm{N}_{2}(300 \mathrm{~K})$

    $\mathrm{V}_{\mathrm{mp}}$ of $\mathrm{O}_{2}(400 \mathrm{~K})$

  3. $\mathrm{V}_{\mathrm{mp}}$ of $\mathrm{O}_{2}(400 \mathrm{~K}) ; \mathrm{V}_{\mathrm{mp}}$ of $\mathrm{N}_{2}(300 \mathrm{~K})$

    $\mathrm{V}_{\mathrm{mp}}$ of $\mathrm{H}_{2}(300 \mathrm{~K})$

  4. $\mathrm{V}_{\mathrm{mp}}$ of $\mathrm{N}_{2}(300 \mathrm{~K}) ; \mathrm{V}_{\mathrm{mp}}$ of $\mathrm{O}_{2}(400 \mathrm{~K})$;

    $\mathrm{V}_{\mathrm{mp}}$ of $\mathrm{H}_{2}(300 \mathrm{~K})$
