Ethyl chloride vapor decomposes by the first-order reaction C2H5Cl --> C2H4 + HCl The activation energy is 249 kJ/mol and the frequency factor is 1.6 X 10^14 s^-1 The rate constant at 730 K is 2.4 x 10^-4 s^-1. 1) Find the fraction of the ethyl chloride that decomposes in 20 minutes at this temperature. ([C2H5Cl]initial - [C2H5Cl]at 1200 sec) / [C2H5Cl]initial =? 2)Find the temperature at which the rate of the reaction would be twice as fast.
