Answer:

temperature, concentration gradient, size of the molecule, viscosity of the media, and the distance between the two points where diffusion happens

Explanation:

Temperature increases the kinetic energy of the molecule so it moves faster and hence the rate of diffusion increases.
the more the concentration gradient the higher the driving force of the process and hence the higher the rate of diffusion.
the more the size of the molecule the higher the inertia it has so the less the rate of diffusion.
the more the viscosity of the medium the more difficult it is for the molecule to move, the less the diffusion rate.
the bigger the distance between the two points of diffusion the more time it needs for the molecule to arrive, and hence the less the rate of diffusion.
