A vessel of volume V contains a mixture of 1 mole of hydrogen and 1 mole of oxygen (both considered ideal). Let ${f}_{1}\left(v\right)dv$ denotes the fraction of molecules with a speed between v and (v+dv) with ${f}_{2}$(v)dv similarly for oxygen. Then,

1. ${f}_{1}\left(v\right)+{f}_{2}$(v) = f(v) obeys the Maxwell's distribution law.

2.  will obey Maxwell’s distribution law separately.

3. neither ${f}_{1}\left(v\right)$ nor ${f}_{2}\left(v\right)$ will obey Maxwell’s distribution law.

4. ${f}_{2}\left(v\right)$ and ${f}_{1}\left(v\right)$ will be the same.
