Question

rate of diffusion is affected by different factors. of the situations below, predict which one would have the fastest rate of diffusion. multiple choice congo red that is highly concentrated in a semisolid methylene blue (molecular weight = 320 g/mol) that is highly concentrated in a liquid methylene blue that is highly concentrated in a semisolid

Explanation:

Diffusion rate is faster in liquids than in semi - solids due to looser molecular packing in liquids. Also, smaller molecules diffuse faster. Among the given options, methylene blue in a liquid has the advantage of the liquid medium which allows for more rapid movement of molecules compared to semi - solids.

Answer:

methylene blue (molecular weight = 320 g/mol) that is highly concentrated in a liquid
