Question 1 45 pts The Finkelstein reaction is a classic SN2 reaction where an alkyl bromide reacts with sodium iodide to produce an iodoalkane and sodium bromide. R-Br + Nal R-I + NaBr Accumulated rate data from operation in a CSTR is shown in Table 1 below and the rate law is was found to be: r = (kCNa CRB1)/(1+(KNaBr CNaBr)+(KRBr CrBr)) Table 1: Rate data for the Finkelstein reaction w Rate Run CRBI CNal CRI CNaBr (mol RBr/kg cat. min) 1 17.1 1 1 0 5 2. 19.7 1 1 0 4. 3 41.6 1 1 0 1 4 41.8 1 1 1 1 5 42 1 1 1 1 6 47 0.5 1 7 71 1 1 1 8 71.3 1 1 4 9 71.3 1 1 0 0 10 71.8 1 1 O 11 117 5 1 O 12 127 10 1 0 13 131 15 1 0 0 14 133 20 1 15 142 1 2. 0 16 284 1 4 0 1. Suggest a mechanism for the reaction based on the rate law (10 marks). 2. Using Table 1, find the rate law parameters (35 marks - Mathematical working: 11 marks. Value of parameters: 8 marks each)
