Diffusivity, mass diffusivity or diffusion coefficient is usually written as the proportionality constant between the molar flux due to molecular diffusion and the negative value of the gradient in the concentration of the species. More accurately, the diffusion coefficient times the local concentration … See more Solids The diffusion coefficient in solids at different temperatures is generally found to be well predicted by the Arrhenius equation: where See more In population dynamics, kinesis is the change of the diffusion coefficient in response to the change of conditions. In models of … See more • Atomic diffusion • Effective diffusion coefficient • Lattice diffusion coefficient • Knudsen diffusion See more For self-diffusion in gases at two different pressures (but the same temperature), the following empirical equation has been suggested: • D is the diffusion coefficient, • ρ is the gas mass density, See more The effective diffusion coefficient describes diffusion through the pore space of porous media. It is macroscopic in nature, because it is not individual pores but the entire pore space that needs to be considered.

The density of a gas is equal to the mass of the gas divided by the volume of the gas. If the volume is held constant one gas is compared with another with another, R 2 R 1 = M 1 M 2. where R is the rate of diffusion in mol/s and M is the ... the hard sayings of jesus study
