Answer:
Frequency = 0.005× 10¹⁷ s⁻¹
E = 0.03 × 10⁻²⁰KJ
Explanation:
Given data:
Wavelength of light = 630.0 nm (630 × 10⁻⁹ m)
Frequency of light = ?
Energy in joule = ?
Solution:
speed of light = wavelength × frequency
Frequency = speed of light / wavelength
Frequency = 3 × 10⁸ m/s / 630 × 10⁻⁹ m
Frequency = 0.005× 10¹⁷ s⁻¹
Energy:
E = h. f
E = 6.63× 10⁻³⁴ Kg. m²/s × 0.005× 10¹⁷ s⁻¹
E = 0.03 × 10⁻¹⁷ j
E = 0.03 × 10⁻¹⁷ j×1 kj /1000 j
E = 0.03 × 10⁻²⁰KJ
Explanation:
The longest wavelength of light with enough energy to break the Cl-Cl bond = 495 nm = 
1) The frequency of the light:


c = speed of light= 


The frequency of the light is
.
2)The energy of a photon of the light:
The energy of the photon is given by : E

h = Planck's constant = 


The energy of a photon of the light is
.
3) The minimum energy of the Cl-Cl bond :
To break single bond of Cl-Cl bond we need energy E= 
1 mole = 
So, in order to break 1 mole of Cl-Cl bond we will need:


The minimum energy of the Cl-Cl bond is 241.83 kJ/mol.

Answer:
I'll give you the graphs that you need to look at:1st order: the graph you need to make is ln[A] vs t. If you get a straight line, the reaction is 1st order and the slope will equal to the rate constant K.2nd order: the graph you need to make is 1/ln[A] vs t. If this graph shows a straight line, the reaction is 2nd order and the slope will equal the rate constant K.
