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?
Calculate the specific heat of molybdenum metal in {rm J/(g cdot ^circ C)}. The specific heat of water is 4.184{rm J/(g cdot ^circ C)}.
Estimate the free energy change (?Grxn) for the following reaction at 298 K, if each gaseous substance is present at p = 0.30 atm. 2H2(g) + O2(g) ? 2H2O(l)
A solution contains 15mL 0.1 M KI, 15 mL of DI water and 5 mL o f3% H2O2. After the decomposition of H2O2 is complete, you titrate the solution with 0.1 M AgNO3. If the catalyst, I-, is not consumed in the reaction and is completely recovered, wha..
Draw all of the stereoisomers that result when (E)-but-2-ene is hydrogenated with D2 over a metal catalyst.
Include all constitutional isomers(except those with carbon-carbon double bond or triple bonds). For each constitutional isomer, identify the functional group and indicate whether there are stereoisomers other than conformers.
How much heat is required to warm 231 g of ice from -45.1°C to 0.0°C, melt the ice, warm the water from 0.0°C to 100.0°C, boil the water, and heat the steam to 173.0°C
A 1.00-mol sample of an ideal monatomic gas is compressed isothermally and irreversibly in one step from 2.50 atm to 6.50 atm at 300.0 K. Calculate G for this process.
How many kilograms of sodium fluoride would be needed to treat an 8.25x10^7 gal reservior?
Important information about Heat and temperature, What is Heat? What is temperature? What are the various properties that account for temperature?
Typically, the concentration of hydronium, H+, or hydroxide,OH- , ions in an aqueous solution is less than 1M . It is not uncommon to have hydronium ion concentrations that are much smaller
10.0 moles of NH3 and 10.0 moles of H2 are introduced into a 2.00 L flask. At equilibrium, 3.0 moles of NH3 gas remain. Calculate Kc for this reaction.
