An 18.5 L chemostat is used to produce a mixed-growth product from a limiting substrate, S, and operates at steady state. Determine the rate of product, P, formation in g/L-h (i.e., DP) and in total g/h, using the following assumptions and parameters. Assumptions: 1. Monod kinetics apply. Assume that substrate is converted primarily to cell (biomass) so you can relate µ to S while assuming S used to form product is negligible. 2. The Luedeking - Piret equation can be applied to determine product formation. 3. Sterile feed. 4. Negligible cell death (kd = 0). Dilution rate, D = 0.77 μmax YM x/s = 0.52 g X/gS Umax = 1.25 h So = 690 mg/L a = 0.47 mg P/g X Ks = = 87.6 mg/L B = 0.63 mg P/gX-h (assumption 1 means that all substrate goes into making new cells- OK to do for an approximation, but not exactly correct, since a product is being formed).

The reversible gas-phase elementary reaction CH₂ CH₂ (a) Write out each step of the algorithm. + H₂ (ethylbenzene styrene + H₂) is carried out in an isothermal CSTR with no pressure drop. The feed enters a volumetric flow rate of vo = 5000 dm³/hour. The feed consists of half ethyl benzene (species A) and half interts on a molar basis and is well mixed before it enters the reactor (I). The pressure in the reactor is 6 atm (so PA0 = 3 atm and P10 = 3 atm, making the initial concentration of A = 0.04 mol/dm^3). The molar flow rate of A is FAO = 200 mol/hr. At the reaction temperature of 640 C, the rate constant isk₁= 5.92 mol/ (dm³ hr * Atm). The equilibrium constant is Kf = 9 atm and the equilibrium conversion is X₂ = * 0.84.

The reaction                             A + B ⎯→ 2Ctakes place in an unsteady CSTR. The feed is only A and B in equimolar proportions. Which of the following sets of equations gives the correct set of mole balances on A, B, and C? Species A and B are disappearing and species C is being formed. Circle the correct answer where all the mole balances are correct.(e) None of the above.

note: please show all the necessary steps/solutions. do not round off in between solutions. correct answers pls. type the answers. thank you..

Short Answer: When you add salt to water, the boiling point is elevated. Briefly connect this to ideal solutions vs non-ideal solutions  and mention how inter-molecular forces are involved. If two components were added together and the resulting mixture approximated an ideal solution, what do you expect to be true about the molecular nature of the two components, do you expect them to be similar or dissimilar, why?
