Use the data in Thermodynamic Properties and the bond energy in Bond Energies to determine the average C-C bond energy in benzene (C6H₁). 4.0✔ kJ/mol Calculate the average of a C-C single bond and a C=C double bond using the bond energies, which is the value expected from the Lewis structure. 4.0✔ kJ/mol The larger calculated value using thermodynamic properties is due to the fact that the pi system is delocalized, which makes the molecule more stable than predicted by simply averaging the C-C bonds.
The enthalpy change for a chemical reaction is the sum of the energy consumed in breaking bonds and the energy released during bond formation. One way to determine the overall energy change for a chemical reaction is to apply Hess’s law to add together a group of reactions which can be arranged such that the chemical equations, when combined, give the overall equation we are trying to characterize. a. Write a balanced chemical equation for the combustion of gaseous propane in gaseous oxygen to produce gaseous carbon dioxide and liquid water. C3H8(g)+ O2(g) ---->CO2(g)+ H2O(g) b. Combine the following equations to determine the enthalpy change for the combustion of 1 mole of propane. Assume that solid carbon is graphite. 3C(s,graphite)+4H2(g)--->C3H8(g) ΔHo = -103.8 kJ/mol C(s,graphite)+O2(g)--->CO2(g) ΔHo= -393.5 kJ/mol H2(g)+1/2 O2(g)--->H2O(g) ΔHo= -285.8 kJ/mol kJ/mol…
