Question

The most influencing factor of diffusivity

Answer 1

explaination: ok let me help you:

diffustion of gases form coal.

the factors that influesncing diffusivity

the diffusivity coeffiecient is dependent on the number of factors, but the most important are the following:

1) type of gas and porous medium interface

2) reservoir pressure

3) gas to gas interface when binary gases are considered

diffusion through porous media:

diffusion coefficient of empty space$/$diffusion coefficient of porous solid

these are all i know hope it helps

over and happy to help:)

Answer 2

Answer:

pressure is the answer.
