nium oxide catalyst [Ind. Eng. Chem. Res. 28, p. 387 (1989)] are shown below. Each reaction follows an elementary rate law. HCHO+21O2k4HCOOHk3CO+H2O2HCHOk2HCOOCH3HCOOCH3k4CH3OH+HCOOH Let A=HCHO,B=O2,C=HCOOH,D=HCOOCH3,E=CO,W=H2O, and G=CH3OH. The entering flow rates are FA0=10mol/s and FB0=5mol/s, and v0=100dm3/s. At a total entering concentration CT0=0.147mol/dm3, the suggested reactor volume is 1,000dm3.

(b) Plot and analyze YC,SAE,SCD, and SDG along the length of the reactor. Note and explain any maximums and the volume at which they occur. (c) Plot and analyze the overall HCOOH yield and overall selectivity of HCOH to CO, of HCOOCH3 to CH3OH, and of HCOOH to HCOOCH3 as a function of the O2. Suggest some conditions to best produce formic acid. Write a paragraph describing what you find. (d) Compare your plot in part (a) with a similar plot when pressure drop is taken into account with =0.002dm3. Note any unusual differences between parts (a) and (d). (e) Suppose that E1=10,000cal/mol,E2=30,000cal/mol,E3=20,000cal/mol, and E4=10,000 cal/mol, what temperature would you recommend for a 1000dm3PFR
