Question

The elementary gas-phase reaction: (CH3)3COOC(CH3)3→C2H6+2CH3COCH3 is carried out isothermally in a flow reactor with no pressure drop. The specific reaction rate at 50oC is 10-4 min-1(from pericosity data) and the activation energy is 85 kJ/mol. Pure di-tert-butyl peroxide enters the reactor at 10 atm and 127oC and a molar flow rate of 2.5 mol/min. Calculate the reactor volume and space time to achieve 90% conversion in: (1) Assume that the reaction is reversible with Kc = 0.025mol2/dm6 and adopt the same value as the specific reaction rate constant for k1(using the PFR and CSTR volumes to achieve 90% equilibrium conversion)
