Hydrocarbon cracking takes place in the gas phase in a tubular reactor (PFR) according to the following reaction: A ------> 2B + 2C Problem data: The feed consists of an equimolar mixture of reagent A and inert. The reaction is of order 2 with a kinetic constant k = 9 dm3/mol.s, Q0 = 1dm3/s, T= 220C, P = 3 atm and the section of the reactor A = 1.0 dm2. The reaction takes place in an isothermal phase and without pressure change.

Determine the volume of a continuous perfectly stirred reactor (CSTR) if the desired conversion rate to A at the outlet of the reactor is 90%.
