Document Summary

Based on the prescribed textbook: h. scott fogler; elements of chemical reaction engineering; fifth edition 2016; prentice hall. We have the following chemical reaction aa bb cc dd a,b,c,d : stoichiometric coefficient. Taking species a as our basic of calculation, we divide the reaction expression through by the stoichiometric coefficient of a. Now we can put every quantity on a per mol of a" basic. The conversion xa is the number of moles of a that have reacted per mole of a fed to the system. At the time t=0 min : number of moles of a = na0. At the time t=t min : number of moles of a reacted = na0 xa. Number of moles of a that remains in the reactor after a time t. Moles of a in reactor at time t=t min. This is the mole balance for batch reactor (br) We use the rate of disappearance of a; -ra for the mol balance. dn.
