Which of the following statements is correct regarding net diffusion?
A
Net diffusion requires an external energy source to occur.
B
Net diffusion is independent of temperature.
C
Net diffusion occurs until the concentration gradient is eliminated.
D
Net diffusion occurs from a region of lower concentration to a region of higher concentration.
Verified step by step guidance1
Understand the concept of net diffusion: Net diffusion is the movement of particles from an area of higher concentration to an area of lower concentration until equilibrium is reached.
Consider the role of energy: Net diffusion is a passive process, meaning it does not require an external energy source. It relies on the kinetic energy of the particles.
Evaluate the effect of temperature: Temperature affects the kinetic energy of particles. Higher temperatures increase particle movement, potentially speeding up diffusion, but diffusion itself is not independent of temperature.
Identify the direction of diffusion: Net diffusion occurs from a region of higher concentration to a region of lower concentration, not the other way around.
Determine when diffusion stops: Net diffusion continues until the concentration gradient is eliminated, meaning the concentration of particles is equal throughout the system.
