Question

Which of the following is not a true statement about diffusion? Diffusion A) is a result of the kinetic energy of atoms and molecules. B) requires no input of energy into the system. C) occurs when particles spread from areas where they are less concentrated to areas where they are more concentrated. D) proceeds until equilibrium is reached.

Answer 1

Diffusion is a passive process of transport where particles move from high to low concentration until equilibrium is reached. The statement that is not true about diffusion is C) occurs when particles spread from areas where they are less concentrated to areas where they are more concentrated.

Step-by-step explanation:

Diffusion is a passive process of transport where a single substance moves from an area of high concentration to an area of low concentration until the concentration is equal across a space. It is driven by the kinetic energy of atoms and molecules, does not require any input of energy, and proceeds until equilibrium is reached. The statement that is not true about diffusion is C) occurs when particles spread from areas where they are less concentrated to areas where they are more concentrated.
