$AB,-r_{1A}=0\mathrm{.}89(mi{n}^{-})CA$

$B2C,-r_{2B}=5\mathrm{.}4(mi{n}^{-})CB$

$2AD,-r_{3A}=0\mathrm{.}45(molK{)}^{-}mi{n}^{-}{C}_{A^2}$

$C$ is desired product $-B$ and $D$ are side products. Calculate overall yield of $C.$ Feed contains pure A with concentration of $1\mathrm{.}2mo\frac{l}{c}.$ Space time is $1\mathrm{.}56$min.
