It takes 614 KJ/mol to break a carbon-carbon bond. Calculate the maximum wavelength of light for which a carbon-carbon bond could be broken by absorbing a single photon. Report the value in nanometer. Pay attention: the unit given is …/mol whereas the questions asks the breaking of ONE carbon-carbon bond. Energy per photon = hc/. h=6.6261034 Js. c=2.998108 m/s. Avogadro constant = 6.0221023.
