**4. Consider the following 3-step reaction mechanism:****Step 1:** \[ \text{H}_2 \rightleftharpoons 2\text{H} \quad \text{(fast)} \]**Step 2:** \[ \text{H} + \text{CO} \rightarrow \text{HCO} \quad \text{(slow)} \]**Step 3:** \[ \text{H} + \text{HCO} \rightarrow \text{H}_2\text{CO} \quad \text{(fast)} \]---**a. What is the overall reaction?**---**b. Identify the intermediates in the reaction mechanism.**---**c. Write a rate law expression for each step of the mechanism including any reversible reactions.**---**d. What is the predicted rate law expression?** *Be sure to only list reactants from the overall equation and not intermediates in the rate law expression.*---In this mechanism, intermediates are substances formed in one step of the reaction and consumed in another. The rate law expressions depend on the slow step and the concentration of the substances involved. The overall reaction combines all steps, cancelling out intermediates.
