Selective oxidation of hydrocarbons is a known method to produce alcohols. However, the alcohols react with the oxygen to produce aldehydes, and the latter react with oxygen to produce organic acids. A 52 mol/s stream consisting of 90.0% ethane and 10.0% nitrogen is mixed with a 37.0 mol/s air stream and fed into a catalytic reactor. The following reactions take place in the reactor: 2 C2H6 + O2 ------> 2 C2H5OH 2 C2H5OH + O2 ------> 2 CH3CHO + 2 H2O 2 CH3CHO + O2 ------> 2 CH3COOH The oxygen conversion is 82.0%, and the concentration of the ethanol in the product stream is three times that of the aldehyde and four times that of the acetic acid.
(a) What is the fractional conversion of ethane? (b) What is the production rate of ethanol?
If the combustion gases consist of CO2, H2O, CO, O2, and N2 that exit at 1200 K and 2 atm, determine (a) the equilibrium composition of the product gases and (b) the rate of heat transfer from the combustion chamber. Is it realistic to disregard t..
A piece of metal with a mass of 151 g is placed in a 50 mL graduated cylinder. The water level rises from 20. mL to 35 mL. What is the density of the metal?
The flask was then shaken until the solution was uniform. A 45.0- sample of this glucose solution was diluted to 0.500 . How many grams of glucose are in 100. of the final solution?
compounds are dissolved in 1.00 L of w ater: 0.220 mol HA (K a = 1.36 x 10 - 3 ), 0. 18 mol NaA, 0.0 8 mol H 2 SO 4 , and 0.08 mol KOH . What is the pH of the resulting solution?
At the begining of the titration being performed in this lab experiement, how do you determine how much naoh should be added at each interval between volume-pH readings? As you approach the equivalence point,
The Al2O3 does not react. If the sample residue weighs 2.675 g, what is the mass fraction of Fe2O3 in the original sample?
Draw the structure ( Fisher projection) of an optically inactive compound z, C4H6O6
Describe how chemical labeling and crystal structures can be used to determine residues important
An empty Erlenmeyer flask weighs 215.7 g. When filled with water (d = 1.00 g/cm3), the flask and its contents weigh 515.4 g.
A photoelectron spectroscopy experiment is conducted in which light with a wavelength of 58.4 nm is directed at a sample of rubidium, resulting in the ejection of the electron
monoprotic acid. Dihydrogen pthalate (H2C8H4O4) is a diprotic acid. An analyte sample contains 0.127 M KHP and 0.0678 M (H2C8H4O4). What volume of a 0.205 M NaOH solution is required to neutralize 25.0 mL of the analyte solution.
