13-11, Set up a stoichiometric table for each of the following reactions and express the concentration of each species in the reaction as a function of conversion Chap 3 Questions and Problems 135 evaluating all constants (e.g., E, O). Then, assume the reaction follows an ele- mentary rate law, and write the reaction rate solely as a function of conver- sion. i.e.. -^= RX). (a) For the liquid-phase reaction CH2-OH 1 CH-CH,+H, H:80: CH-OH the initial concentrations of ethylene oxide and water are 1 lb-nof/ft and 3.47 Ib-mol/ft? (62.41 lb/ft + 18), respectively. If k = 0.1 dm /mol s at 300 K with E = 12.500 cal/mol. calculate the space-time volume for 90% conversion at 300 K and at 350 K. (b) For the isothermal, isobaric gas-phase pyrolysis CH C,H, + H purc cthane enters the flow reactor at 6 ani and 1100 K. How would your equation for the concentration and reaction rate change if the reac- tion were to be carried out in a constant-volume batch reactor
