Question: How would you modify Table 6-2 for a. A constant-volume gas-phase reaction, and b. A variable-volume gas-phase reaction? Table 6-2 1. Mole balances: BR dNAdt=rAV

How would you modify Table 6-2 for
a. A constant-volume gas-phase reaction, and
b. A variable-volume gas-phase reaction?

Table 6-2 1. Mole balances: BR dNAdt=rAV dNBdt=rBV dNCdt=rCV dNDdt=rDV PFR PBR CSTR dFAdV=rA dFAdW=rA' V=FAO-FA-rA We shall continue the algorithm using a PBR as an example. 2. Rates: Rate Law -rA'=KACAGCBB Relative Rates rA'-a=rB'-b=rC'c=rD'd then rB'=barA'rC'=-carA'rD'=-ddrA' Stoichiometry: Concentrations CA=CTOFATOFTTPCB=CTOFBTOFTTPCC=CTOFCTOFTTpCD=CTOFDTOFTTPdpdW=-a2pFTFTOTTO,p=PPO 4. Combine: Appropriate reactor mole balance on each species Rate law o Concentration for each species o
