List three characteristics that influence the rate of simple diffusion of small molecules.

Solution

Answer= Three characteristics that influence the rate of simple diffusion of small molecules

1] Particle size = Rate of diffusion is inversaly proportional to particle size

Since the heat of environment is the energy source for diffusion the smaller particles moves at a faster rate than larger paricles at a given temperature

2] temperature = Rate of diffusion is directly proportional to temperature

As temperature increses rate of diffusion also increases

At high temp. particles move faster because more energy is available to diffuse them

3] Concentration difference = rate of increses as conc. difference increases

The substance diffusing between 2 areas exibits a conc. diffference as the particle diffuse from one side of the wall to other side

4] particle distance = rate of diffusion is directly proportional to particle distance

it takes longer for a particle to diffuse when it is further away than it does for a particle that is closer to the point of diffusion
