Which amongst the following statement is incorrect about diffusion?
Increase in temperature causes increase in rate of diffusion.
The rate of diffusion is directly proportional to the gradient of diffusion pressure.
The rate of diffusion is independent of the density of particles.
Diffusion always occurs along the concentration gradient.
The rate of diffusion is inversely proportional to the square root of density of particles. (Graham's diffusion law)
