The ratio of average speed of an oxygen molecule to the r.m.s. speed of a 'N_2' molecule at the same temperature is

Which one of the following molecules has the largest dipole moment? (Electro-negativity values of elements concerned are: B=2.0, Cl=3.0, F=4.0, H=2.1, N=3.0, O=3.5, P=2.1, S=2.5)

The fraction of gaseous molecules having speed in between u and u+ du as governed by Maxwell distribution of speeds is given by (dN_(u))/(N) = 4pi ((M)/(2pi RT))^(1//2) exp (-"Mu"^(2)//2 RT) u^(2) du Graphically this distribution is shown in fig. Based on this distribution, answer the following three question The maximum value of (dN/N)/du corresponds to most probable speed. With increase in temperature, this maximum fraction
