Question
Does increasing the surface area of a solid reactant increase, decrease or have no effect on the frequency of collisions between the reacting particles?
Solution
Increasing the surface area of a solid reactant increases the frequency of collisions between the reacting particles. Here's why:
-
The rate of a chemical reaction is directly related to the frequency of collisions between reacting particles. The more often they collide, the faster the reaction occurs.
-
When the surface area of a solid reactant is increased, more of its particles are exposed to the other reactant. This can be achieved by grinding or crushing the solid into smaller pieces.
-
With more particles exposed, there is a higher chance of collisions occurring between the reactant particles.
-
Therefore, increasing the surface area of a solid reactant increases the frequency of collisions, which in turn increases the rate of the chemical reaction.
