Explanation:
An Exothermic reaction releases energy into the surroundings and so the products have more potential energy then the reactants. The enthalpy change is a negative value. Whereas, an endothermic reaction involves the absorption of energy into the system and so the reactants have more potential energy than the products. The enthalpy change is a positive value. This is clearly represented in energy profile diagrams.
2C4H10 + 13O2 -> 8CO2 + 10H2O
The frequency and energy of most energetic of these photons is
Hz and
J respectively.
The high energy photons will have least wavelength. Taking the given less wavelength for calculation of frequency and energy of photons.
λ = 2200 Å
Also, we know, 1 Å =
m
So, λ = 
λ =
<em> </em>m
Now, calculating frequency using the formula -
c = fλ, where c is speed of light, f is frequency and λ is wavelength.
We know, c =
m/s
f = c/λ
f = 
frequency =
Hz
Now, calculating Energy through the formula -
E = hf, where E is energy, h is planck's constant and f is frequency
Value of planck's constant =
Js
E =
*
Energy =
J
Thus, frequency and energy of photons is
Hz and
J respectively.
