About this Simulation

This simulation models how reaction rates change with varying concentration of reactant 1, temperature, and the amount and surface area of reactant 2. Students observe particle collisions in real-time and investigate how each factor independently influences the speed of chemical reactions.

Learning objectives: Identify how concentration changes affect collision frequency and reaction rate | Explain the relationship between temperature and molecular kinetic energy on reaction rate | Analyze how surface area of a solid reactant influences the rate of reaction
