5. (12%) A liquid-phase reaction A →2R was performed in a CSTR with a volume of 5 L. In
the reaction, the reactant A was fed to the CSTR at a concentration of I molL. The researcher
intended to find a rate expression for this reaction by carrying out the experiments at different
conditions, which were summarized in the following Table. Please determine the reaction
order and the activation energy of this reaction.
