An important reaction in the formation of photochemical smog is the photodissociation of no2: no2 + hv > > > no(g) + o(g) the maximum wavelength of light that can cause this reaction is 420 nm. a) in what part of the electromagnetic spectrum is light with this wavelength found? b) what is the maximum strength of a bond, in kj/mol, that can be broken by absorption of a photon of 420-nm light? c) write out the photodissociation reaction showing lewis-dot structures.

Explanation:

The maximum wavelength of light that can cause this reaction is 420 nm.

a) The wavelength given lies in the range of visible light range that is from 400 nano meters to 700 nano meters.

The light with wavelength of 420 nm is found in the range of visible light.

b)The maximum strength of a bond :

where,

E = energy of photon = Energy required to break single molecule of nitrogen dioxide

h = Planck's constant =

c = speed of light =

= wavelength =

Energy required to break 1 mole of nitrogen dioxide molecules:

(1 J = 0.001 kJ )

285.13 is the maximum strength of a bond, in kJ/mol, that can be broken by absorption of a photon of 420-nm light.

c) the photodissociation reaction showing Lewis-dot structures is given in an image attached.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
