Question

It takes 1.57 × 10-18 ) of energy to break a nitrogen-nitrogen triple bond, wavelength = 251 nm be able to break this bond? Will a photon of light with Planck's constant h = 6.63 x 10-34 Js. The speed of light c = 3.00 x 108 m/s. Yes, because the frequency of the light is low enough Yes, because the energy of the photon is high enough No, because the energy of the photon is too high No, because the frequency of the light is too high No, because the wavelength of the light is too high

Answer 1

Answer:

No, because the wavelength of the light is too high.

Explanation Ezhe m Let us calculate the energy of photon using the formula d Where E= photon energy h= plank's constant (6-63x1034 JS) e = speed of light (3:0x108 m/s) 1= wave length of light (251 mm) since '¿' value given in mis we have to convert il value into d=251 nm = 251 X10 x109 (inm = 10%) 6-63 X10 x1034 JŚ 251 X10 x109 11 19.89 x10269 => E=0.079243 x10'*) 251x109 E = 7.9243x16'91 given that energy to break a nitrogen-nitrogen triple bond calculated energy of light is smaller than the required energy. to bienk NEN. J 7.9243 x16 19 J 3.0x188 requires 1.57x1018 y, but the 1.57x1018 So NEN Note: can not break. the energy of photon is inversely proportional to Wavelength of photon, so photon, so the 1 of photon is too high, hence energy is low. the
