Question

estion 5 of 19 Determine the frequency and energy for light with a wavelength of 706.6 nm. kJ/mol What is the color of light with a wavelength of 706.6 nm? Refer to the electromagnetic spectrum as needed. Determine the wavelength and energy for light with a frequency of 5.867 x 10's-1. kJ/mol What is the color of light with a frequency of 5.867 x 101 s 1? Refer to the electromagnetic spectrum as needed.

Answer 1

Details answer given in the attachment...

Now in kJ/mol unit IY Es 2.8 X 1069 J med for conversion multiply by avogadro no. (6.022x100 and lopty by 1000 to convert KJ Convert Divided 23 200 kj - J A 6.022x10 1.J X for Kl/mol > 1.J X 6-022 x 103 / 1 Kg (1000 kJ = 17) 22X ro 4ky 1000] I mol 2-881.0 J x 60022Xlors 1.6868 KJ - 1000J Imol E = 1.686810² kJ/moe Ams 07 - 168.6 kJ/mol

so frequency (U) = 5.13810" si] Ano Now Energy of light we know - E=mc and a so Edo E = 6.62X10 Is X s. 13 x 10" 5 J. E= 3.39 x 10 Energy in kJ (mal E= 3.38×10197 = 3-39x10 % x 6,0 20x10 kg = 2,04 x 10² Inol 10905 mer Energy = 2.04 x 10² kJ/mol Ans LE=204.0kJ/mol

d = 3.37x107m 1 m= 100 nm d = 3. 37x107x10 nm d=337 nm sold in nm = 337 nm nm I Ans ar What Ans = Colour of light with Colour of light is Energy of 256.1 kI /mol Blue
