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?
Determine the pH of the acid solution before the titration begins and the pH at the equivalence point when 50.0 mL of the NaOH has been added. The Ka of HF is 7.2*10^-4
The concentration which remains after 20 minutes is 80 mg/L. Determine the reaction order and the rate constant (with appropriate units).
a solid block of exactly 100.0 cm cubed has a mass of 153.6g. Determine its density.Will the block sink or float on water.
Consider the reaction when aqueous solutions of sodium acetate and potassium sulfide are combined.
Gaseous HBr has an absorption band centered at about 2645 cm-1 consisting of a series of lines approximately equally spaced with an interval of 16.9cm-1.
The ketone used was cyclopentanone and the aldehyde used was benzaldehyde. First cyclopentanone was dissolved in 95% ethanol. Then benzaldehyde was added along with NaOH to the mixure. The solution was then mixed creating the aldol condensation pr..
