In an ideal flow tube at $75C$ there should be a volume$-$stable reaction of

the type:

$2A+BC+D$

take place. The reaction depends on the reactant $A$ in the second

order. The production output of $C$ is $1,430mo\frac{l}{h},$ the initial concentrations are

$CA=1,640mo\frac{l}{m^3},cc=0.$ The conversion should be $0\mathrm{.}55,$ the reaction time is

$0\mathrm{.}87h.$

a$)$ How large is the volume flow in the inlet?

b$)$ What volume does the reactor have to have?
