calculate the enthalpy of vaporization of SO2 at -25degree celsius , if the same at its b.pt.(-10degree celsius) be 5950cal/mol. given the molar heat capacities, Cp(l)=20.6cal/mol and Cp(g)=9.3cal/mol
The bond energy of NO is 632 kl/mol and that of each N-O bond in N02 is 469kj/mol. Using lewis structures and and the average bond energies explain the difference between the two molecules and the fact that the bond energies of the two bonds in NO2 are the same.
