About this app
Enthalpy and Hess's Law is an interactive high-school chemistry learning app about reaction heat. Adjust reactant and product energy levels to compare exothermic and endothermic reactions, combine reaction steps to verify Hess's law, and estimate reaction enthalpy from bond energies.
Use cases
- High-school students studying enthalpy and reaction heat
- Chemistry teachers demonstrating exothermic and endothermic reactions
- Learners practicing Hess's law calculations
- Students exploring bond breaking and bond formation energy
- Classroom or self-study chemistry activities
Features
- Interactive reactant and product enthalpy controls
- Visual comparison of exothermic, endothermic, and reverse reactions
- Two-step versus direct-path Hess's law simulator
- Bond energy calculation using broken and formed bonds
- Guided missions with reset and next controls
- SVG diagrams showing reaction paths and energy levels
