In a study of the reaction of pyridine (C;H;N) with methyl iodide (CH;I) in a benzene solution, the following set of initial reaction rates was measured at 25°C for different initial concentrations of the two reactants: [C,H;N] (mol L1) [CH;I] (mol L-) Rate (mol Ls') 1.00 x 10-4 1.00 x 10-4 7.5 x 10-7 2.00 x 10-4 4.00 x 10-4 2.00 x 10-4 3.0 x 10- 2.00 x 10-4 6.0 x 10-6 (a) Write the rate expression for this reaction. (b) Calculate the rate constant k and give its units. (c) Predict the initial reaction rate for a solution in which [C;H;N] is 5.0 × 10-5 M and [CH;I] is 2.0 × 10-5 M.
