Question

question 1 of 10 consider the following geometric solids. a sphere with a ratio of surface area to volume equal to 0.15 m⁻¹. a right circular cylinder with a ratio of surface area to volume equal to 2.2 m⁻¹. what results would you expect if these two models were compared in a diffusion test? a. the rate of diffusion would be faster for the right cylinder. b. the rate of diffusion would be slower for the right cylinder. c. the rate of diffusion would be the same for the two models. d. the rate of diffusion would be faster for the sphere.

Explanation:

Step1: Recall diffusion principle

Diffusion rate is related to surface - area - to - volume ratio.

Step2: Compare ratios

The right circular cylinder has a higher surface - area - to - volume ratio ($2.2\ m^{-1}$) than the sphere ($0.15\ m^{-1}$).

Step3: Determine result

Higher ratio means faster diffusion for the right cylinder.

Answer:

A. The rate of diffusion would be faster for the right cylinder.
