Identify the speed distribution functions of Ne, Ar and Kr with the curves in the figure above:
(a)Ne-A, Ar-B, Kr-C
(b)Ne-B, Ar-C, Kr-A
(c)Ne-C, Ar-B, Kr-A
(d)Ne-C, Ar-A, Kr-B
Answer
Answer (as printed): C
Explanation
Maxima in the curve corresponds to most probable speed of the gas . OR- 𝐶dR = d As MNe < MAr < MKr . So , C (M.P)Ne < C(M.P)Ar < C (M.P)Kr So , curve C corresponds to Ne , B to Ar and A to Kr CSIR JUNE 2015
