Verified step by step guidance1
Understand the concept of diffusion: Diffusion is the process by which particles spread from an area of higher concentration to an area of lower concentration, driven by the concentration gradient.
Identify the concentration gradient: A concentration gradient exists when there is a difference in the concentration of particles in two areas. Particles will naturally move from the area where they are more concentrated to where they are less concentrated.
Recognize the natural direction of diffusion: Particles move from areas of high concentration to areas of low concentration to achieve equilibrium, where the concentration of particles is uniform throughout.
Consider the random motion of particles: While the overall movement is from high to low concentration, individual particles move randomly due to kinetic energy, but the net movement is towards equilibrium.
Apply this understanding to the problem: The correct answer is that particles naturally diffuse from areas of high concentration to low concentration, as this is the direction that leads to equilibrium.
