$For the reaction profile shown: a. This profile shows an \[ \text{exothermic} \] reaction. b. What is the approximate value of the activation energy? \[ \text{[ Select ]} \] **Graph Explanation:** The graph illustrates a reaction profile, plotting Potential Energy (PE) in kilojoules (kJ) against the reaction pathway. - The y-axis represents Potential Energy (PE), measured in kilojoules (kJ), ranging from 0 to 250 kJ. - The x-axis is labeled as "Reaction Pathway," showing the progress of the reaction. On the graph: - The curve begins at a lower PE level, increases to a peak, and then decreases to an even lower PE level, indicating an exothermic reaction. - The peak of the graph represents the highest energy state, which is the activation energy. The approximate activation energy appears to be around 200 kJ.$
