Interpretation Introduction
(b)
Interpretation:
Explanation for the modified action of arsenite due to the addition of more citrate.
Concept introduction:
The citric acid cycle is a catabolic process. It is a series of chemical reactions in which the stored energy of the body is released by the oxidation of acetyl-Coenzyme A. Oxaloacetate is an intermediate of the Krebs cycle which binds to the acetyl-CoA in the synthesis of citrate. Arsenite is a chemical compound that contains an arsenic oxo-anion in which the arsenic has oxidation state +3.

Oxygen is transferred to the particle surface by diffusion, where it is consumed in the reaction C + O₂ →> CO₂. The reaction rate is first order and of the form No2 = k₁C₁₂(r), where k₁ = 0.1 m/s. Neglecting changes in r, determine the steady-state O₂ molar consumption rate in kmol/s. At 1450 K, the binary diffusion coefficient for O2 and CO2 is 1.71 x 10ª m²/s.arrow_forward2. (20 points) Consider combustion of hydrogen gas in a mixture of hydrogen and oxygen adjacent to the metal wall of a combustion chamber. Combustion occurs at constant temperature and pressure according to the chemical reaction 2H₂+ O₂→ 2H₂O. Measurements under steady-state conditions at 10 mm from the wall indicate that the molar concentrations of hydrogen, oxygen, and water vapor are 0.10, 0.10, and 0.20 kmol/m³, respectively. The generation rate of water vapor is 0.96x102 kmol/m³s throughout the region of interest.

- 3. (15 points) Living cells homogeneously distributed (immobilized) with an agarose gel require glucose to survive. An important aspect of the biochemical system design is the effective diffusion coefficient of glucose (A) into the cell- immobilized gel. Consider the experiment shows below where a slab of the cell-immobilized gel of 1.0cm thickness is placed within a well-mixed aqueous solution of glucose maintained at a concentration of 50 mmol/L. The glucose consumption within the cell-immobilized gel proceeds by a zero-order process given by R₁ = -0.05 mmol/(L min). The solubilities of glucose in both the water and the gel are the same; that is, the concentration of the glucose on the water side of the water-gel interface is equal to the concentration of the glucose on the gel side of the water gel interface. A syringe is mounted at the center of the gel carefully excises a tiny sample of the gel for glucose analysis.
