Butadiene $($A$)$ will react with ethylene $($B$)$

$C_1{H}_6+C_2{H}_4{k}_4{C}_6{H}_6(Adibatic$ Reactor$)$

is the gas phase Reaction at temperature above $500C.$ If an equimolar mixture of butadiene and ethylene at $450C$ and $1$atm is fed to a reactor. Determine the spoce time for $\%10$ conversion of Butadiele.

$K={10}^8{e}^{-\frac{27500}{R}T},R=1,987ca\frac{l}{m}ol*K$

$H_R=-30000ca\frac{l}{m}ol(450C)\frac{?}{b}$

$ar(C{)}_{C_4{H}_{}}=36,8ca\frac{l}{m}ol*K\frac{?}{b}$

$ar(C{)}_{C_2{H}_4}=20,2ca\frac{l}{m}ol.K\frac{?}{b}$

$ar(C{)}_p{C}_{810}=59\mathrm{.}5ca\frac{l}{m}ol.K$
