Reaction Rate & Activation Energy

by Anonymous

Change collision frequency with concentration, increase particles crossing the activation-energy barrier with temperature and catalysts, and explore the half-life of a first-order reaction.

About this app

Reaction Rate and Activation Energy is an interactive chemistry learning app with three simulations: concentration and collisions, activation energy, and first-order reaction half-life. Adjust concentration to see collision counts follow the square of concentration, change temperature or add a catalyst to explore the activation-energy threshold, and step through time to observe repeated halving.

Use cases

  • High school chemistry students studying reaction rates
  • Teachers demonstrating collision theory and catalysts
  • Learners comparing concentration, temperature, and catalyst effects
  • Science classes exploring first-order reaction half-life

Features

  • Interactive concentration control with collision counts from 1Γ— to 16Γ—
  • Temperature and catalyst controls showing particles above the activation-energy threshold
  • First-order half-life simulation with adjustable elapsed time and half-life
  • Visual stages, legends, equations, and explanatory feedback
  • Mission-based activities with reset and next controls
