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 limiting reactant in each of the following reactions. Circle (Just label) the formula for the limiting reactant in each problem.
What is the pH after 13.3 mL of base is added? The Ka of butanoic acid is 1.5 X 10^-5.
The mechanism by which these compounds kill insects and people is unknown. D. These compounds kill insects and people by stimulating acetylcholinesterase, an enzyme of the nervous system.
Which would involve the emission of a higher frequency of light, the transition of an electron in an H atom from the n = 5 to the n = 3 level or a similar transition in an X atom?
A sample of 6.022 g of CH4 is enclosed in a 12 L container at 402 K. What is its pressure in atmospheres
Calculate the equilibrium partial pressure of bromine gas. No approximations can be made because the equilibrium constant is too large. I2 (g) + Br2 (g) 2IBr (g)
How much of the solution is needed?
Write the mass balances for K+ and the phosphate species in a soln prepared by mixing .025mol KH2PO4 plus
Acid-catalyzed dehydration of an alcohol most closely resembles an E1 mechanism when secondary and tertiary alcohols are involved.
A 0.2088g sample of an unknown monprotic acid is titrated with 22.10 ml of 0.1000 mol/L KOH. The pH of the solution after the addition of 22.10 ml of base is 5.02. What is the Ka for the acid?
Prior to their phaseout in the 1980s, chemicals containing lead were commonly added to gasoline as anti-knocking agents. A 1.805 g sample of one such additive containing only lead, carbon, and hydrogen was burned in an oxygen rich environment.
