== == The elementary gas-phase reversible reaction 3A + 2B + 4C is to be carried out isothermally with no pressure drop in a PFR with an equal molar feed of A and B, with Cao = 2 mol/L. For the operating conditions, ka = 2 L4/mol4.s and Kc = 0.5 L/mol. a. What is the concentration of B initially? b. What is the limiting reactant? c. Set up a stoichiometric table. d. What is the exit concentration of each species when the conversion of A is 25%? e. Write -ra solely as a function of conversion. f. What is the equilibrium conversion, Xe (what will conversion be when the reaction reaches equilibrium)? g. What is the rate when conversion is 0%, 0.5Xe, and 0.99Xe
