Q

factors affecting rate of movement

A

hugh tempreture will increcrease the rate of movment as there is more energy more kinetic energy so particles move faster
a high concentration gradient will increase rate of movment
a short diffusion distance will increase the rate of diffusion
large surface area to volume ratio will increase rate of movment as there is more area for the particles to move
