Explain effect of mass of molecule from the basis of Maxwell - Boltzman speed distribution. |
|
Answer» Solution :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.
