Explain effect of mass of molecule from the basis of Maxwell - Boltzman speed distribution.

Explanation

At fixed temperature speed of heavy molecules less than speed of light molecules.
For example, speed of `N_(2)` gas is more than speed of `Cl_(2)` gas. (Mass of `N_(2)= 28 mu`) and (Mass of `Cl_(2)=71 mu`)
Speed of `N_(2)gt` Speed of `Cl_(2)` .... (consdtant T)
`u_(mp) N_(2)gt u_(mp)Cl_(2)` .......(constant T)
where, `u_(mp)=` Most probable speed
`= (("maximum speed of"),("maximum molecules"))`
Value if most Probable speed of `N_(2)` is more than value of most probable speed of `u_(2)`.
Speed distribution curve of `N_(2)` and `Cl_(2)` is given in below figure.
