How Does pressure change diffusion?

Pressure influences diffusion by altering the concentration gradients and the kinetic energy of molecules. At higher pressures, gas molecules are forced closer together, which can enhance the rate of diffusion as the increased molecular collisions facilitate movement. Conversely, in liquids, increased pressure may have a minimal effect on diffusion rates compared to gases, as liquid molecules are already closely packed. Overall, pressure can either accelerate or decelerate diffusion depending on the state of matter and the specific conditions involved.
