The elementary gas phase reaction AB+2C is carried out isothermally in a membrane reactor with no pressure drop. The specific reaction rate is 104min1 and equilibrium constant KCC=0.025mol2/dm6. Pure A enters the reactor at 10atm and 127C and a molar rate of 2.5mol/min. B flows out through the sides of the reactor and the transport coefficient is kC=0.08s1. It is required to determine the reactor volume to achieve 90% conversion. Develop the necessary equations to be solved by polymath. Number ONL Y the equations you will use in the program
