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 C2H5OH2 C2H5OH + O2 ------> 2 CH3CHO + 2 H2O2 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?
Distinguish between a differential rate law and integrated rate law by writting one of each type
A solution is prepared by adding 0.500 g of solid NaCl to 50.0 mL of 0.100 M {CaCl_2}. What is the molarity of chloride ion in the final solution? Assume that the volume of the final solution is 50.0 mL.
what adjustment should be made to the mobile phase to bring the compound off sooner? why?
Calculate the pH during the titration of 100.0 mL of 0.200 M HCl with 0.400 M NaOH. First what is the initial pH (before any NaOH is added)? - What is the pH after 38.4 mL of NaOH are added?
A 0.521-g sample of a compound is dissolved in enough water to form 100.0 mL of solution. This solution has an osmotic pressure of 2.45 atm at 25°C. If each molecule of the solute dissociates into two particles (in this solvent), what is the molar..
A 20.00mL sample of H3Y was titrated with 0.1000 M NaOH. The first equivalence point was reached after the addition of 14.98mL of base. The second equivalence point was reached after the addition of 30.03mL.
A bag of potato chips contains 595 mL of air at 30.0 degrees celcius and a pressure of 770 mm Hg. Assuming the bag does not break, what will be its volume at the top of a mountain where the pressure is 438 mL and the temperature is 8.00 celcius?
Approximate the percent increse in waste size that occurs when a 155lb person gains 40.0 lbs of fat. Assume that the volume of the person can be modeled by a cylinder that is 4.0 feet tall.
Use the Rydberg equation to calculate the wavelength in nanometers of the spectral line of hydrogen for which n2 = 4 and n1 = 2.
The tank is first evacuated, and then it is connected to a 50.0 L cylinder of compressed nitrogen gas. The gas pressure in the cylinder, originally at 21.5 atm, falls to 1.55 atm without a change in temperature. What is the volume of the tank?
