Due: Start of Lesson 8, 15 Feb 18 1. Consider the reaction between pyridine (CHN) and iodomethane (CHI) at 25 °C in benzene The reaction was run at varying concentrations of C,HsN and CH.I. The initial rate of formation of the product, N-methylpyridinium iodide, was measured 1.00 4.00x 10 6,00 x 10* 2.00 x 10 a Calculate the reaction order with respect to CHal Rate 2 Cs 2.00 b Calculate the feaction order with 0.50.5 c. Identify the overall reaction order d. Determine the rate law for the reaction and write the expression for the rate law, ie, "rate e Calculate the rate constant and give its units. D O f Predict the intahateofformation ofthe product (inMS) when [CsH5N], is 5.00×10 5 Mand [CH11 is 200 x 10-f at 25 °C :S OL Imols-s.ooflo.sM , 2,06 ylo. s of 11 Februarv 2018 Page 1 of 2 in

Explanation / Answer

All the work you have done is correct except rate law.

Your reactants are pyridine and methyl iodide and you have determined the order w.r.t pyridine as well as with methyl iodide as first order.

Hence, Rate law is

Rate = k [C5H5N]1 [CH3I]1

or  Rate = k [C5H5N] [CH3I]
