The elementary gas phase reaction, $2A+BC,$ is carried out in a PFR with no pressure drop. The feed is equal molar in A and $B,$ and the entering concentration of $A$ is $0\mathrm{.}1mo\frac{l}{d}{m}^3.$

a$)$ Setup a stoichometric table

b$)$ Write the rate law solely as a function of conversion, and with $C_{A0}=2mo\frac{l}{d}{m}^3$ and $k_A=2d\frac{m^6}{m}ol*s.$
