Chemistry And Sustainability Concepts For STEM Students Practice Test

Which factors influence the rate of a chemical reaction?

Concentration Temperature Catalysts All of the above

Correct Answer:

All of the above

Explanation:

Rate depends on how often reacting molecules meet and how effectively those meetings lead to products. Increasing concentration raises how often collisions occur, speeding up the rate as there are more chances for reaction. Temperature shifts the kinetic energy distribution: at higher temperatures, more molecules have enough energy to surpass the activation energy, so more collisions are productive and the rate goes up. Catalysts provide an alternative, lower-energy pathway to products, allowing the reaction to proceed faster at the same temperature without being consumed. Since each of these factors can increase the rate, all of the listed factors influence how fast a reaction occurs.
