The rate of diffusion is influenced by the surface area-to-volume ratio of an object. A higher surface area-to-volume ratio generally leads to faster diffusion because there is more surface area available for particles to interact with the surroundings.
In this case, the sphere has a lower surface area-to-volume ratio (0.3 m¹) compared to the right circular cylinder (2.1 m¹). Therefore, we would expect the rate of diffusion to be slower for the sphere (option C) and faster for the right circular cylinder (option D).
Since the sphere has a smaller surface area relative to its volume, there is less surface area available for particles to diffuse through compared to the right circular cylinder. Consequently, the diffusion process would be slower for the sphere. On the other hand, the right circular cylinder with a larger surface area relative to its volume would provide more opportunities for particles to diffuse, resulting in a faster diffusion rate.
