Question

use the pA vs t data and find the slope (i.e. rate) graphically or numerically at pa = 0.04.atm

Table P5.28 1, sec Pa, atm 1, sec Pa, atm 0 20 40 60 80 100 1.00 0.80 0.68 0.56 0.45 0.37 140 200 260 330 420 0.25 0.14 0.08 0.04 0.02 stoichiometry of the reaction is 2A →R+S. What size (in liters) operating at 100°C and 1 atm can treat 100 mol A/hr in a feed consisting of 20% inerts to obtain 95% converson of A? 5.29. Repeat the previous problem for a mixed flow reactor.
