A vessel of volume V contains a mixture of 1 mole of hydrogen and 1 mole oxygen (both considered as ideal). Let f_1 (v)dv, denote the fraction of molecules with speed between v and (v + dv) with f_1 (v)dv, similarly for oxygen. Then,

Q: A vessel of volume V contains a mixture of 1 mole of hydrogen and 1 mole oxygen (both considered as ideal). Let f₁ (v)dv, denote the fraction of molecules with speed between v and (v + dv) with f₁ (v)dv, similarly for oxygen. Then,

(a) f₁ (v) + f₂ (v) = f(v) obeys the Maxwell’s distribution law

(b) f₁ (v) , f₂ (v)obeys the Maxwell’s distribution law separately

(c) Neither f₁ (v) , nor f₂ (v) will obey the Maxwell’s distribution law

(d) f₂ (v) and f₁ (v) will be the same

Ans: (b)
