Chapter 11, Problem 85AP

A commercial drink was diluted with distilled water in a 1:9 and 1:24 ratio. Each was transferred to a burette and 25 mL of the Benedict's reagent used in number one was titrated with these samples. For the 1:9 ratio, 8.61 mL of the diluted drink was used to reach the endpoint while for the 1:24 ratio, 21.41 mL of the diluted drink was necessary for the blue color to disappear. a. Determine the concentration of glucose (mg/mL) in the sample that was diluted 10-fold b. Determine the concentration of glucose (in mg/mL) in the sample that was diluted 25-fold c. Determine the concentration of glucose (in mg/ml) in the undiluted sample?

on 1: 2A The gas phase decomposition (k = 0.001 s) is carried out in a plug flow reactor at 300°C and 10 atm. Reactor feed rate of A is 2 mol/s, and contains 75 mol% inert. Determine the length of 0.0254 m diameter pipe needed to reach 99% conversion. Question 2: A+2B C+D 2028.616 The liquid-phase reaction is first order in both A and B with k=0.0017m³/mol.min at 461°K with E-11273Cal/mol. The initial entering concentrations of A and B are 1.8 mol/m³ and 6.6mol/m³, respectively. What is the rate of reaction (X=90) at 298°K? Question 3: For The following reaction A-1.2611X10-5 Calculate the equilibrium conversion and concentration for the gas phase reaction A+B 2C The reaction carried out in a flow reactor with no pressure drop. the feed is equal molar which is 3 at a temperature of 400 K and 10 atm. At this temperature, Kc= 8(dm³/mol)². Question 4: PA+B C + 2D ll in the following table for CB and X.assuming as a liquid phase & initial concentration of CA-1N CA 1 CB 0.15 X 0.9 0.8 0.7…
