Answer to Question #131669 in Physical Chemistry for Zain Abbas

Question

A mixture of ammonia isotopes containing 0.5 moles of NH2D and 2.0 moles of NHD2 is allowed to equilibrate, producing a mixture of NH3, NH2D, NHD2 and ND3

a. Ignoring the N atoms (because they are not exchanging), determine the most probable distribution once equilibrium is achieved.

Answer 1

A mixture of ammonia isotopes containing 0.5 moles of NH2D and 2.0 moles of NHD2 is allowed to equilibrate, producing a mixture of NH3, NH2D, NHD2 and ND3

in case of ND₃ HAVE HIGHER MOLAR MASS THAN NH3, NH2D, NHD2

speed of gas molecule is inversly proportional to molar mass .

speed of gas molecule order = NH3 > NH2D > NHD2 > ND3 .
