The reaction A →→ 2B + 2C with overall rate Inet consists of the following elementary reactions. Step 1: Step 2: with rate constants ki and k-1 with rate constant k₂ Step 3: with rate constant k3 AI + 2B I→ 2J J→C I and J are reactive intermediates in the above mechanism. Assume PSSH on all reactive intermediates. A. What are the stoichiometric numbers for each step? Draw a rate arrow diagram involving 1₁, 11, 12, and r3 and show how these relate to Inet. B. Derive a rate expression for Inet applying the PSSH for all reactive intermediate species. C. If the first step is quasi-equilibrated, then derive the rate expression for Inet. D. Compare your answers in parts B and C and use this to provide the justification for QE in this system. E. Draw the rate arrow diagram for the reaction sequence assuming that QE applies for step 1. Clearly label all rates and their relationship to Inet. F. Draw the rate arrow diagram for the reaction sequence assuming that step 1 is practically irreversible. Clearly label all of the rates being graphed and their relationship to Inet. G. Under what conditions would step 1 be irreversible and what would the expression for Inet be in that case?
