Initiation: C2H5ONO2 ^ C2H5O + NO2 Propagation: C2H5O ^ CH3- + CH2O CH3- + C2H5ONO2 ^ CH3NO2 + C2H5O Termination: 2C2H5O k-X CH3CHO + C2H5OH (a) What rate expression is consistent with this mechanism? (b) Since these investigators carried out their study in a stirred flow reactor, they were able to measure the reaction rate directly as a function of ethyl nitrate concentration. They have reported the following data. Rate (moles/m3 ksec) 13.4 12.2 12.1 23.0 20.9 Ethyl nitrate concentration (moles/m3 ) 0.0975 0.0759 0.0713 0.2714 0.2346 Is the proposed mechanism consistent with this data? What are the order of the reaction and the rate constant that they observed experimentally?
