The аppаrаtus belоw is used at ASU tо measure the kinetics (rate cоnstants) of very fast chemical reactions that can occur in a few millionths of a millionth of a second. It uses a frequency quadrupled pulsed Nd:YAG laser with light output at 266 nm. Does 266 nm light have enough energy to break chemical bonds? To answer this question you need to know that chemical bonds have strengths around 200 - 400 kJ/mol. Calculate the energy of 266 nm light, in kJ/mol, to 1 decimal place. E = Na.h.c/λ, where: Na = Avogadros number: 6.022 x 1023 h = Plank constant: 6.626 x 10-34 J.s c = speed of light: 2.99 x 108 m.s-1 λ = the wavelength of the light You will need to do some unit conversions
