The protective action of ozone in the atmosphere comes through ozone's absorption of UV radiation in the 230 to 290 nm wavelength range. What is the energy, in kilojoules per mole, associated with radiation in the wavelength range?

Answer 1

E = hc/wavelength
Remember h is Planck's constant
c is speed of light in m/s
wavelength must be in m
Solve for E in J and this is for 1 photon. Multiply by 6.02E23 to obtain J/mol and convert to kJ.
Do this for 230 nm and 290 nm and I would quote the range in energy.

Answer 2

413.11 kJ/mol

Answer 3

520-413kj/mol
