**Transcription for Educational Website****Graph Explanation**The graph shown depicts the potential energy changes during a chemical reaction as it progresses. The horizontal axis represents the reaction progress, while the vertical axis indicates potential energy. The graph includes four main points labeled A, B, C, and D, with peaks at B and C, suggesting transition states, and valleys, indicating intermediates.- Point A: Initial state of the reactants.- Point B: First transition state, a peak representing an energy barrier.- Point C: Second transition state, another peak with a higher energy barrier than B.- Point D: Final state of the products, a stable energy state following the reaction.**Questions**a. How many intermediates are there in the reaction?b. How many transition states are there?c. Which is the fastest step in the reaction?d. What is the reactant in the rate-determining step?e. Is the first step of the reaction exothermic or endothermic?f. Is the overall reaction exothermic or endothermic? **Educational Website Content: Reaction Mechanics****Subsection: Reaction Steps and Thermodynamics**- **d.** What is the reactant in the rate-determining step?- **e.** Is the first step of the reaction exothermic or endothermic?- **f.** Is the overall reaction exothermic or endothermic?**Section 6: Potential Energy Diagram**The potential energy diagram for the reaction \( \text{A(g)} \leftrightarrows \text{D(g)} \) is shown below.*Diagram Analysis:*- The diagram typically illustrates the energy changes during the reaction from reactants to products.- It shows different energy levels for reactants, intermediates, transition states, and products.- Exothermic reactions have products with lower energy than reactants, whereas endothermic reactions have products with higher energy.- Look for peaks representing transition states and valleys for stable intermediates or final products.(Note: Since the diagram is not visible here, this explanation provides an overview of how to interpret such diagrams.)
