Question
Explain how increasing the concentration of reactants can affect the rate of a chemical reaction.
Answer
Increasing the concentration of reactants generally increases the rate of a chemical reaction because there are more particles available to collide with each other. This leads to a higher frequency of successful collisions, which can result in more product formation over time.
Explanation
This question assesses the application of knowledge regarding concentration and reaction rates. The answer clearly connects increased concentration to increased collision frequency, demonstrating an understanding of the underlying principles of reaction kinetics.
Common mistake
Misunderstanding Reaction Rates
Students often think that barriers to reaction only affect the speed of the reaction and do not understand that they can prevent reactions from occurring altogether.
Emphasize that barriers to reaction can slow down or completely stop a reaction, and provide examples of how catalysts can lower these barriers to increase reaction rates.
