![**Reaction Mechanism for the Synthesis of Formaldehyde**
Consider the three-step mechanism for a reaction proposed for the synthesis of formaldehyde:
- **Step 1:** \( \text{H}_2 \rightarrow 2\text{H} \) (Fast, endothermic)
- **Step 2:** \( \text{H} + \text{CO} \rightarrow \text{HCO} \) (Slow, endothermic)
- **Step 3:** \( \text{H} + \text{HCO} \rightarrow \text{H}_2\text{CO} \) (Fast, exothermic)
The reaction is overall exothermic.
**a. What is the overall reaction?**
\[ \text{H}_2 + \text{CO (g)} \rightarrow \text{H}_2\text{CO (g)} \]
*Draw a potential energy diagram for this reaction. Be sure to include all necessary identities such as \( E_a \), \( \Delta H \), TS (transition states), reactants, products, etc.*
**Potential Energy Diagram:**
The diagram would typically feature:
- An initial increase in energy for the endothermic steps (Step 1 and Step 2), indicating the energy required to activate the reaction.
- A peak representing the transition state, with labels for \( E_a \) (the activation energy).
- A subsequent energy drop post-transition state, indicating the exothermic nature of Step 3.
- The initial potential energy level for reactants (\( \text{H}_2 + \text{CO} \)).
- The final potential energy level lower than that of the reactants, for the products (\( \text{H}_2\text{CO} \)), representing the overall release of energy (\( \Delta H \)).
In a complete diagram, the x-axis represents the reaction progress, while the y-axis represents the potential energy.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F57638993-6d33-4396-984b-2e3f32f46fd1%2F5af1664d-f6fa-4278-9b43-c3d670a6de94%2Fi5cmyq4_processed.jpeg&w=3840&q=75)
