You have studied the gas-phase oxidation of HCI by 02: 4 HCl(g) + O₂(→2 H₂O + 2 Cl₂0 You find the reaction to be first order with respect to HCI and first order with respect to O₂. You propose the following mechanism: HCl( + O₂() →HOOCI(g) HOOCI(g) + HCl → 2 HOCI(g) HOCI + HCl →H₂O+ Cl₂(8) (a) Confirm that the elementary reactions add to give the overall reaction. (b) Based on the experimentally determined rate law, which step is rate determining? (c) What are the intermediates in this mechanism? (d) If you are unable to detect HOCI or HOOCL among the products, does this disprove your mechanism?
