Effect of Surface Area on Reaction Rate

Overview

When a solid lump is subdivided into fine powder, the surface area increases and more particles are exposed for collisions. This results in an increased frequency of collisions and therefore a faster rate of reaction.

Learning objectives

After completing this module, you will be able to :
- Identify the effect of surface area of solid reactant on rate of reaction.
- Illustrate graphically the effect of surface area of solid reactant on rate of reaction.
- Explain the effect of increasing surface area on reaction rate using collision theory.
- Apply this concept in practical problems.
