Detailed explanation-1: -Complete answer: The electrical charges of the diffusion particles are the only factor that does not have an effect on the rate at which diffusion occurs.

Detailed explanation-2: -The rate of diffusion in cells is affected by factors such as temperature, concentration gradient, size of the molecule, and the presence of a membrane.

Detailed explanation-3: -The rate of diffusion is affected by the concentration gradient, membrane permeability, temperature, and pressure. Diffusion takes place as long as there is a difference between the concentrations of a substance across a barrier.

Detailed explanation-4: -Several factors affect the rate of diffusion of a solute including the mass of the solute, the temperature of the environment, the solvent density, and the distance traveled.
