Textbook Question
Chapter 4, Problem 4.30P
A garment to protect the wearer from toxic agents may be made of a fabric that contains an adsorbent, such as activated carbon. In a test of such a fabric, a gas stream containing 7.76 mg/L of carbon tetrachloride (CC14) was passed through a 7.71-g sample of the fabric at a rate of l.OL/min, and the concentration of CCI4 in the gas leaving the fabric was monitored. The run was continued for 15.5 min with no CCI4 being detected, after which the CC14 concentration began to rise.
- How much CC14 was fed to the system during the first 15.5 min of the run? How much was adsorbed? Using this information as a guide, sketch the expected concentration of CCI4 in the exit gas as a function of time, showing the curve from f = 0 to r» 15.5 min.
- Assuming a linear relationship betw een amount of CC14 adsorbed and mass of fabric, w hat fabric mass w ould be required if the feed concentration is 5 mg/L, the feed rate 1.4 L/min, and it is desired that no CCI4 leave the fabric earlier than 30 min?

- Amoxicillin is an antibiotic packaged as a powder. When it is used to treat babies and small animals, the pharmacist or veterinarian must suspend it in water, so that it can be administered orally with a medicine dropper. The label says to dispose of unused suspension after 14 days. It also points out that refrigeration is required. In the context of this chapter, what is implied in the latter two statements?arrow_forward3. Cobalt (II) Sulfide (CoS) is more soluble in aqueous solutions when you add an inert salt like potassium nitrate, even though neither potassium nor nitrate show up in the BCE for the dissolution reaction. The solubility product constant for cobalt (II) sulfide is Ksp = 5 x 10-22 making it a remarkably insoluble substance. Your job is to figure out the molar solubility in pure water, then the molar solubility in a 0.25 M KNO3 aqueous solution and finally to express the change as a percent difference. To make it easier (and faster) please use the Debye-Hückel limiting law: log Yx = -0.510 Zx2² (μ)1/2 to obtain the required activity coefficients and make a simple assumption about the ionic strength of water - rather than solving for it in an iterative process.arrow_forwardIn the reaction 2C(s) + O_2(s) ----> 2CO(g), what is the volume ratio between O₂ and CO? a 1:1 b 2:1 c. 1:2 d. 2:2arrow_forward

- The enzyme urease is widely used for determining urea concentration in blood. The Michaelis constant for urease at room temperature is 2.0 mM and k2 = 2.5 × 10^3 s^-1 at pH = 7.5. Based on the kinetic experiment, when 4.76 mM urease was used, the initial rate of the reaction was determined to be 8.1 M/sec. What is the concentration in unit of mM of urea in blood? Please keep your answer to two decimal place. Please convert all concentration unit to mM in calculation.

The reaction is represented by the equation above. Diagram 1 represents the uncatalyzed reaction and diagram 2 represents the catalyzed reaction one hour after the reactants were mixed. Which of the following correctly explains the experimental results represented in the particle diagrams? S Although the reaction is thermodynamically favorable because AG° 0 based on the value of K, but the addition of a catalyst improved the orientation of the reactants during collisions, allowing the catalyzed reaction to proceed in one hour. The reaction is not thermodynamically favorable because AG° > 0 based on the value of K, but the catalyzed reaction could proceed in one hour because it has a lower AH and a higher AS.arrow_forwardSome sulfuric acid is spilled on a lab bench. It can be neutralized by sprinkling sodium bicarbonate on it and then mopping up the resultant solution.
