- The liquid phase reaction between trimethylamine and n-propyl bromide was studied by immersing sealed glass tubes containing the reactants in a constant temperature bath. The results at 139.4o C and initially using 0.1 mol/L of each of the reagents are as follows:

t(min)	12,8	35	59	120
conversion(%)	11,2	25,7	36,7	55,2

From these data, determine the reaction order, rate constant, and half-life.
