1. An elementary gas phase reaction is carried out in a 5 m^3 PFR reactor at 50 C and 5 bar. The reaction is: A+D-> B+2C and its rate constant is 10.3 dm^3 /mol s What is the expression for the volume of the reactor with respect to the conversion of A? Consider that the reactor is fed with a volumetric flow rate of 5 m^3 / with an equimolar mixture of A and D.
