For the irreversible reaction: $A+2BC+3D$

$1\mathrm{.}1$ If the reaction has elementary kinetics, what is the rate law?

$1\mathrm{.}2$ What is the $$ for this reaction?

$1\mathrm{.}3$ The feed consists of a liquid$-$phase solution of A and $B$ in a stoichiometric ratio plus some $D$ and an inert component, I. There is no $C$ in the feed. The $D$ in the feed is present in a molar ratio of $\frac{1}{5}=\frac{F_{D0}}{F_{A0}}$ and the inert is present so that $\frac{1}{5}$ of the total feed flowrate is inert.

$1\mathrm{.}3\mathrm{.}1$ Calculate ${}_D.$

$1\mathrm{.}3\mathrm{.}2$ Calculate ${}_{\text{I}}.$
