Which of the following gas will have highest rate of diffusion? — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Rate of diffusion is inversely proportional to the square root of molecular weight. 1 R MW Here, Molecular weight ( 3 NH ) =17 Molecular weight ( 2 N ) =28 Molecular weight ( 2 CO ) = 44 Molecular weight ( 2 O ) =32 As it can be seen 3 NH has lowest molecular weight among them. Thus, it will have highest rate of diffusion.
