Consider hypothetical elements X2 and Y2. Suppose the enthalpy of formation of the compound XY is – 84 kJ/mol, the bond energy for X2 is 105 kJ/mol, and the bond energy for Y2 is 58 kJ/mol.
A)Estimate the XY bond energy, Ed, in units of kJ/mol.
B)If the dissociation of a X-Y molecule were accomplished by the absorption of a single photon whose energy was exactly the quantity required, what would be its wavelength in nm?
C)Would a green-light photon (λgreen=550 nm) be able to break the above X-Y bond? Explain.
Use average bond energies together with the standard enthalpy of formation of C( g) (718.4 kJ/mol) to estimate the standard enthalpy of formation of gaseous benzene, C6H6( g). (Remember that average bond energies apply to the gas phase only.) Compare the value you obtain using average bond energies to the actual standard enthalpy of formation of gaseous benzene,82.9 kJ/mol. What does the difference between these two values tell you about the stability of benzene?
