Play an AI-generated podcast conversation about this lesson

What factors affect the rate of diffusion?

Photosynthesis, acidity of solutions, kinetic energy
Tonicity, dialysis, molecule size
Silver nitrate test, equilibrium, chlorophyll absorption
Temperature, concentration gradient, molecular mass of particles (correct)

How does temperature impact the rate of diffusion?

Lower temperatures increase molecular motions
Lower temperatures increase the concentration gradient
Higher temperatures increase the diffusion rates (correct)
Higher temperatures decrease kinetic energy

What happens to diffusion rates as molecules get closer to equilibrium?

They remain constant
They slow down (correct)
They stop completely
They speed up
