photochemical dissociation produces a normal oxygen atom and an oxygen atom 2 5ev more energetic than normal one also - Chemistry - Atomic Structure

Question

photochemical dissociation produces a normal oxygen atom and an
oxygen atom 2 5ev more energetic than normal one also the average
bond energy of oygen itno noraml oxygen is 498kj/mol determine the
longest wavelength required for photochemical dissociation of
oxygen

Geetha · Accepted Answer

Bond energy of oxygen per molecule = 498 × 1036
022 × 1023 = 8
26 × 10-19 JEnergy required for  photochemical decomposition of one molecule of O2= 8
26 × 10-19 J + 2
5 × 1
6 × 10-19 J  (1 ev = 1
6 × 10-19 J)  = 1
226 × 10-18 Jλ = hcE = 6
626 × 10-34 × 3 × 1081
226 × 10-18 = 16
214 × 10-8 = 162 nm

photochemical dissociation produces a normal oxygen atom and an oxygen atom 2.5ev more energetic than normal one. also the average bond energy of oygen itno noraml oxygen is 498kj/mol. determine the longest wavelength required for photochemical dissociation of oxygen.
