Refer tо the fоllоwing proposed mechаnism for the reаction between moleculаr chlorine and nitrogen monoxide. NO (g) + Cl2 (g) → NOCl2 (g) (fast) NOCl2 (g) + NO (g) → 2 NOCl (g) (slow) a. Write the chemical equation for the overall reaction process. b. Identify the reaction intermediate(s), if any, in the mechanism. c. Assuming the second step of the mechanism is rate determining, predict the rate law for the reaction. d. Given the mechanism outlined above, on your provided scratch paper draw a plausible potential energy diagram for the following chemical reaction, you can assume that the reaction above is exothermic. Label the following components on your potential energy diagram: reactants, products, transition states, intermediates, activation energy.
