Question

question 1
which of the following factors influence diffusion rates?
select all that apply
□ electrical charge of particles
□ molecular size
□ temperature
□ distance

Explanation:

• Molecular size: Smaller molecules diffuse faster as they can move through spaces more easily.
• Temperature: Higher temperature increases kinetic energy of molecules, speeding up diffusion.
• Distance: Greater distance means molecules have to travel more, slowing diffusion (Fick's laws relate diffusion to distance).
• Electrical charge of particles: Diffusion (passive transport) is not influenced by charge as it's about random molecular motion, unlike active transport or ion movement with charge - related forces. So molecular size, temperature, and distance affect diffusion rates.

Answer:

B. Molecular size, C. Temperature, D. Distance
