Sagot :

Final answer:

Factors affecting diffusion rate: molecular size, temperature, and solution density.


Explanation:

Molecular size: Larger molecules move more slowly than smaller molecules during diffusion due to the increased difficulty in passing through spaces between molecules.

Temperature: Higher temperatures increase molecular energy, leading to faster movement and higher rates of diffusion.

Solution density: A denser solution slows down diffusion as molecules struggle to move through the medium, while less dense solutions facilitate faster diffusion.
