Question

question 1
how does solvent density affect the diffusion rate?
denser solvents allow faster diffusion.
solvent density affects the direction of diffusion.
higher solvent density decreases the diffusion rate.
as solvent density decreases, diffusion slows down.

Explanation:

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. In denser solvents, the particles of the solvent are more closely packed together. This makes it more difficult for the diffusing particles to move through the solvent. So, higher solvent density means more resistance for the diffusing particles, which decreases the diffusion rate.

Answer:

Higher solvent density decreases the diffusion rate.
