Answer 2

The ratio of average speed of CO₂ and N₂O is

Average Speed: It is the sum of speed of all the molecules divided by the total number of molecules.

Formula for calculating Average speed of molecules:

                                =  $\sqrt \frac{8RT}{\pi M}$

                    where, R = Universal Gas Constant

                                 T = Temperature

                                 M = Molecular weight of Gas

Average speed of CO₂ = $\sqrt \frac{8RT}{\444\pi }$      (molecular weight of CO₂ = 44gm)

Average speed of N₂O = $\sqrt \frac{8RT}{44\pi }$      (molecular weight of N₂O = 44gm)

By calculating, ratio of average speed of CO₂ and N₂O = 1:1

Therefore, at constant temperature the ratio of average speed of carbon dioxide and nitrous oxide will be 1:1
