Reaction Rate & Activation Energy
by Anonymous

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 1× to 16×
- 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
