Consider the following reaction: C2H2 (g)+ O2 (g) → 2 CO2 (g) + H2O (g) Given of CO2 (g) = -393.5 KJ/mol, H2O (g) = -241.8 KJ/mol, and for C2H2 (g) = 227.4 KJ/mol, calculate for this reaction. How many KJ of heat is released when 0.440 kg of carbon dioxide produced?
Dinitrogen tetroxide decomposes to form nitrogen dioxide in a second-order reaction: N2O4(g) → 2NO2(g) At 400.0 K, the rate constant for this reaction has been measured to be 2.9 × 108 L/(mol • s). Suppose 0.222 mol of N2O4(g) is placed in a sealed 41.7-L container at 400.0 K and allowed to react. What is the total pressure inside the vessel after 32.9 ns has elapsed? (R = 0.0821 (L • atm)/(K • mol)) a. 0.183 atm b. 0.175 atm...
Methane (CH4) and oxygen (O2) react to form formaldehyde (CH2O) (reaction #1), with a competing side reaction (#2) in which methane and oxygen form carbon dioxide (CO2): CH4(v) + O2(g) -> CH2O(v) + H2O(l) (reaction #1) CH4(v) + 2O2(g) -> CO2(g) + 2H2O(l) (reaction #2) A fresh feed of an equimolar gas mixture of CH4 and O2 is combined with a recycle stream and fed to a reactor. The single-pass conversion of CH4 is 30% and the selectivity of CH2O...
Calculate the heat of reaction AH for the following reaction: 2 CH 4(g)+302(9)2 CO(g) + 4H2O(g) You can find a table of bond energies by using the Data button on the ALEKS toolbar. Round your answer to the nearest kJ/mol. kJ X mol
Use bond energies to calculate ?Hrxn for the
reaction.
2H2(g)+O2(g)?2H2O(g)
Note: The answer is NOT 442 kJ or 442kJ/mol
It gave me this hint when I got the answer wrong: The bond
energies of H?H, O=O, and H?O are provided in the introduction. To
determine the enthalpy of this reaction, sum all of the bond
energies for the reactants (accounting for stoichiometric ratios as
is), and subtract the bond energies for the product. Note how many
bonds are in each...
