65. Which of the following pairs will diffuse at the same rate through a porous plug (a) CO, 2NO (b) 22,CONO (c) 33,PHNH (d) NO62HC
According to grahm's law of diffusion Molecular weight is inversely proportional to rate of diffusion.It means that those molecules which has same molecular weight can diffuse the at same rate. In the bove option D has the same molecular weight for both NO,C2H6 that is 28. Hence option D is correct.
