Q4.18: In order to break a F-F bond, an energy of 153 kJ is required per mole of F-F bonds. What wavelength of light would be required to break a single F--F bond? Answer: nm
Part ACalculate the bond energy per mole for breaking all the bonds in methane, CH4.Express your answer to four significant figures and include the appropriate units.ΔHCH4 =1656 kJmolCorrectIn CH4, the energy required to break one C−H bond is 414 kJ/mol. Since there are four C−H bonds in CH4, the energy ΔHCH4 for breaking all the bonds is calculated asΔHCH4=4×bond energy of C−H bond=4×414 kJ/mol=1656 kJ/mol CH4 moleculesPart BCalculate the bond energy per mole for breaking all the bonds of oxygen,...
