The reaction 2 NO (g) + 2 H2 (g) ↔ N2 (g) + 2 H2O (g) is second order in [NO] and first order in [H2]. A three-step mechanism has been proposed. The first, fast step is the formation of N2O2. The third step, also fast, is N2O (g) + H2 (g) ↔ N2 (g) + H2O (g). Propose an entire three-step mechanism where the second step is slow, and show that it conforms to the experimentally determined reaction order.
The mechanism for the reaction described by the equation CH,NC(g) CH, CN(g) is suggested to be k1 (1) A(g) + M(g) = A" (g) + M(g) k-1 k2 * (2) А (g) → B(g) where A(g) is CH, NC(g), M(g) is any gas molecule, A* (g) is CH,NC*(g) (an energized gas molecule), and B(g) is CH,CN(g). Assuming that [A* ] is governed by steady-state conditions, derive the rate law for the production of CH, CN(g) in terms of [A], [M], and the appropriate k values.
Part B The reaction of ethyl acetate with sodium hydroxide, CH3COOC2H5(aq) + NaOH(aq) = CH3COONA(aq) + C2H5OH(aq) is first order in CH3COOC2H5 and first order in NaOH.

Consider the proposed mechanism for the reaction, CHCI3(g) + Cl2(g) HCI(g) + CCI4(g) --> (1 - fast) Cl2(g) = 2 CI(g) (2 - slow) CI(g) + CHCI3(g) HCI(g) + CCI3(g) --> (3 - fast) CI(g) + CCI3(g) --> A student proposes that the reaction rate law is rate = k [CI] [CHCI3]. Why is this incorrect? %3D (Choose the best answer.) The student's proposed rate law is not based on the rate-determining step in the mechanism. The rate orders with respect to Cl and CHCI3 match the stoichiometric coefficients for these compounds in step (2). It is always the last step in a mechanism that determines the rate law and CHCI3 is not in step (3). Clis in the proposed rate law. CI is an intermediate and only reactants and products that appear in the ove reaction equation may be in the reaction rate law.

The rate law for the reaction 2 NO (g) + Cl2 (g) ⇄ 2 NOCl (g) is given by the rate=k[NO][Cl2]. A mechanism involving these steps has been proposed for the reactionNO (g) + Cl2 (g) ⇄ NOCl2 (g)NOCl2 (g)+ NO (g) ⇄ 2 NOCl (g)(2a) If this mechanism is correct, what does it imply about the relative rates of these two steps (e.g. How do the rates of reaction compare? Which is slow?)(2b) What is the reaction intermediate in this mechanism?
