What are the main sources of the energy consumed in the

Solution: Step1: Given, the energy required to break the Cl-Cl bond in Cl = 242 kJ/mol 2 = 242 x 10 J/mol 3 23 = (242 x 10 J) / (6.023 x 10 ) [1 mol = 6.023 x 10 photons] = 40.18 x 10 -20J -19 = 4.02 x 10 J. Step2: According to Planck’s quantum theory of radiation, the amount of energy associated with a quantum(in case of light, the quantum of energy is often called photon) of radiation is proportional to the frequency of light, E = h
