Q$)$ Substance $\text{'}A\text{'}$ in liq phase reacts to produce $R$ and

$s$ as follows

A feed $(C_{AO}=1,C_{R_0}=0,C_0=0)$ enters two $MFR$ in series

$({}_1=2\mathrm{.}5(min),{}_2=5(min)),$ knowing the compositions in the ist

reactor $(C_{A_1}=0\mathrm{.}4,C_{R_1}=0\mathrm{.}4,C_{S_1}=0\mathrm{.}2)$ find the composition

learing the second reactor.
