$.$ A mixed flow reactor is being used to determine the kinetics of a reaction whose stoichiometry is A B$.$ For this purpose various flow rates of an aqueous solution of $100$ mmole A$/$liter are fed to a $1-$liter reactor, and for each run the outlet concentration of A is measured. Find a rate equation to represent the following data. Also assume that reactant alone affects the rate. vo liter$/$min Ca$,$ mmole$/$liter $146202450$
