The rate constant for the conversion of cyclopropane into propene was determined at several temperatures. Use a graphing calculator or standard graphing software to make an Arrhenius plot and calculate the activation energy, Ea, for the reaction. k(s-1) 1.8 x 10-4 2.7 x 10-3 3.0 x 10-2 800. 850. 900. 0.26 Eg = 270 kJmol- Calculate the rate constant, k, at 544.0 °C. k = 2.6 x10° $
