The process called diffusion
A) is the tendency for solute molecules to move from an area of high concentration to an area of low concentration.
B) is the product of random movement of all atoms, molecules, and ions in a solution.
C) always produces net movement of materials against the concentration gradient for that material.
D) is both the tendency for solute molecules to move from an area of high concentration to an area of low concentration and is the product of random movement of all atoms, molecules, and ions in a solution are correct.
E) is both the tendency for solute molecules to move from an area of high concentration to an area of low concentration and always produces net movement of materials against the concentration gradient for that material.

Question

Quizplus · Accepted Answer

Diffusion is the process in which solute molecules move from an area of high concentration to an area of low concentration. This is due to the random movement of all atoms, molecules, and ions in a solution. Therefore, option D, which states that both the tendency for solute molecules to move from an area of high concentration to an area of low concentration and the product of random movement of all atoms, molecules, and ions in a solution are correct, is the best choice. Option E is incorrect since diffusion doesn't always produce net movement of material against the concentration gradient.
