Question

Which of the following solutions has the potential to diffuse the fastest?

1) One with large molecules as opposed to smaller ones
2) One with a higher concentration of molecules as opposed to one with a lesser concentration
3) One under low pressure as opposed to one under high pressure
4) One at a low temperature as opposed to one at a higher temperature
5) All of these have the potential to diffuse equally fast

Answer 1

The fastest potential diffusion occurs in a solution with a high concentration of small molecules at a high temperature and in a less dense solvent, as these conditions profoundly influence the rate of molecular movement and diffusion.

Step-by-step explanation:

The solution that has the potential to diffuse the fastest is one with a higher concentration of molecules, as opposed to one with a lesser concentration. This is due to the extent of the concentration gradient: a greater difference in concentration drives a more rapid diffusion. On the other hand, larger molecules move more slowly than smaller ones and thus diffuse more slowly. When it comes to temperature, a higher temperature increases the energy and movement of the molecules, which consequently increases the diffusion rate. As for pressure, diffusion is not directly affected by pressure in the manner described.
