Question 1 Set up an stoichiometric table for the plug flow reactor and answer on this basis the following questions: What is the volumetric gas flow (m3/min) to and from the reactor, measured at the reactor temperature and pressure? What is the molar concentration of A, B and C (mol/m3) in the effluent (outlet) gas mixture ?

The decomposition of di-tert-butyl peroxyde to ethane and acetone occurs by a gas phase reaction: (CH3)3COOCCOH)3C2H6+2CH3COCH3 or AB+2C The reaction is an irreversibel, first order reaction in the peroxyde concentration with the reaction rate expression: rA=kCA where A denotes the di-tert-butyl peroxyde. At 80C the rate constant is given by: k=0,0147min1. An industrial scale tubular reactor, operating at continuous, steady state conditions, must be designed to meet the following conditions: Reactor operating conditions: By external heat exchange the reactor is held isothermal at a temperature of 100C, and the reactor pressure is constant at 10 bar. The reactor feed consists of pure A with a feed rate of: FA0=25mol/min.90% of the entering A must be converted to products. Plug flow can be assumed and the reaction mixture is an ideal gas. Kinetic studies of the reaction has shown that the rate constant obeys Arrhenius law with an activation energy of 85kJ/mol
