The following liquid-phase reactions were carried out in a CSTR at 325K. 3AB+C2C+A3D4D+3C3Er1A=k1ACAr2D=k2DCC2CAr3E=k3ECDCCk1A=7.0min1sk2D=3.0mol2mindm6k3E=2.0molmindm3 (i) PFR. Now assume the reactions take place in the gas phase. Use the preceding data to plot the molar flow rate's selectivity and y as a function of PFR volume up to 400dm3. The pressure drop parameter is 0.001dm3, the total concentration entering the reactor is 0.2mol/dm3, and v0=100 dm3/min. What are S~D/E and S~CDD
