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.
