How does the distance between particles affect the rate of diffusion?
A
The rate of diffusion is highest at medium distances.
B
The rate of diffusion is unaffected by the distance between particles.
C
The rate of diffusion increases as the distance increases.
D
The rate of diffusion decreases as the distance increases.
Verified step by step guidance
1
Understand that diffusion is the process by which particles spread from an area of higher concentration to an area of lower concentration.
Recognize that the rate of diffusion is influenced by several factors, including the distance between particles.
Recall that as the distance between particles increases, it takes longer for particles to move from one point to another, thus decreasing the rate of diffusion.
Consider the analogy of a person walking: the longer the distance they have to travel, the more time it takes, which is similar to how particles diffuse over longer distances.
Conclude that the correct statement is: 'The rate of diffusion decreases as the distance increases,' because increased distance results in slower diffusion rates.
