Problem $3(25/100)$: A liquid reactant stream $($reactant concentration is $1mo\frac{l}{L})$ passes

through two CSTRs in series. The concentration of $A$ in the exit of the first reactor is $0\mathrm{.}5mo\frac{l}{L}.$

The reaction is second$-$order with respect to A and the volume ratio is $\frac{V_2}{V_1}=2($second reactor

is two times larger$).$

Find the concentration of $A($in $mo\frac{l}{L})$ in the exit stream of the second reactor.
