An elementary second order adiabatic reaction A+ B CD ? + is taking place in a CSTR. The feed to the reactor is equimolar A and B at concentrations of 2.4 mol/liter. The entering temperature is 300 K. The volumetric flow rate is 15 lit/min. Following are some other data characterizing the reaction. 0 0 0 0 20 Btu/lb.mol- F 15 Btu/lb.mol- F 15 Btu/lb.mol- F 20 Btu/lb.mol- F (300 ) 7000 cal/mole of A (300 ) 0.00045 l/mol-min 12,000 cal/mol A B C d p p p p Rx C C C C H K k K E = = = = ? =- = = What volume of the reactor is required for 75% conversion?
