A $746\mathrm{.}5$ liter CSTR is being used to produce chemical B using the following reaction:

AlongrightarrowB

The reactor has one inlet and one outlet and operates at a constant density of $55lb\frac{m}{f}{t}^3.$

The mass flow rate into the reactor is $13\mathrm{.}2k\frac{g}{h}r$ and the concentration of species A leaving the reactor is $0\mathrm{.}3$ gmole$/$L$.$

The reaction kinetics are described by the following rate equation: $r_{rxn}=k{c}_A^2,$ where $k$ has been measured be $4\mathrm{.}6{10}^{-4}\frac{L}{g}$mol$-s.$

What is the rate of consumption of species $A$ in units of moles$/$hr$?$
