b$.$ An exothermic non$-$elementary liquid phase reaction $AB+C$ is to be carried out isothermally in a continuous process. The feed of the reactant is to be supplied at $21mo\frac{l}{h}$ with initial concentration of $2\mathrm{.}25mo\frac{l}{d}{m}^3.$ Laboratory data in TABLE Q$1$ was taken under identical conditions.
