1.	For a PFR, the area under the curve \(\frac{1}{-r_A}\) vs XA gives ____(a) \(\frac{F_{A_0}}{dV} \)(b) \(\frac{dV}{F_{A_0}} \)(c) dVCA0(d) dVFA0The question was posed to me in an interview for internship.My question comes from Kinetics of Homogeneous Reactions topic in division Kinetics of Homogeneous Reactions of Chemical Reaction Engineering
Answer» Correct option is (b) \(\FRAC{dV}{F_{A_0}} \) For EXPLANATION I would say: For a PFR, FA0dXA = (-RA)dV. \(\frac{dXA}{(-rA)}\) gives . Area under the CURVE gives \(\frac{dV}{FA0}. \)
