Verified step by step guidance1
Understand the concept of diffusion: Diffusion is the process by which particles spread from an area of high concentration to an area of low concentration. It is driven by the kinetic energy of the particles.
Recognize the relationship between temperature and kinetic energy: As temperature increases, the kinetic energy of particles also increases. This means that particles move faster at higher temperatures.
Relate kinetic energy to diffusion rate: Since diffusion is dependent on the movement of particles, an increase in kinetic energy (due to higher temperature) will result in particles moving more rapidly.
Conclude the effect of temperature on diffusion: With increased particle movement, the rate of diffusion will also increase. Therefore, an increase in temperature leads to a higher rate of diffusion.
Summarize the correct answer: Based on the understanding of diffusion and the effect of temperature on kinetic energy, the correct answer is that an increase in temperature increases the rate of diffusion.
