Transcribed Image Text:The diagram depicts an energy profile for a chemical reaction, illustrating the changes in energy as the reaction progresses. Here's a detailed description of the graph: 1. **Reactants**: The energy level at the beginning of the reaction represents the energy of the reactants, labeled as "1". This is the starting point of the reaction progress. 2. **Activation Energy (Ea)**: The highest point on the curve shows the activation energy required for the reaction, labeled as "2". This is the energy barrier that must be overcome for the reaction to proceed. 3. **Energy Released**: The vertical line labeled "3" represents the energy released during the reaction. It shows the difference in energy between the reactants and the products. 4. **Products**: The final energy level, labeled as "4", indicates the energy of the products. This level is lower than that of the reactants for exothermic reactions, indicating that the reaction releases energy. The x-axis is labeled "Reaction progress," while the y-axis is labeled "Energy," showcasing how energy changes as the reaction goes from reactants to products.
