Factors affecting rate of diffusion Flashcards
1
Q
Concentration gradient
A
The greater the concentration difference between the two compartments, the faster the subtance will diffuse
2
Q
Distance of travel
A
Decreases, the further the particle must diffuse, the longer it will take and the slower the rate of diffusion
3
Q
The surface area of a membrane
A
The greater surface area of the membrane, the greater the diffusion
4
Q
Thickness of membrane
A
The thicker the membrane, the longer it will take to diffuse
5
Q
An increase of temperature in the membrane
A
Increase, more heat energy more kinetic energy
6
Q
Particle size
A
Asmaller particle will diffuse faster than a larger molecule
