Question

How much energy, in kilojoules per mole, is released when an electron makes a transition from n=5 to n=2 in an hydrogen atom? Is this energy sufficient to break the H-H bond (436 kj/mol is needed to break this bond)

Answer 1

You will need to use Rydberg's equation to solve for λ. Second use λ to obtain energy of the photon.


1/λ = RZ^2(1/n1^22 - 1/n2^2)

Where n2 > n1

Solve for λ

Next solve for the energy of a photon:

E=hf


Remember,

C=λf

f=C/λ

E=h(C/λ)

C=speed of light
F=frequency
H=plank's constant

Answer 2

R = Rydberg's constant (1.0973731568539(55) x 107 m-1)

Answer 3

Typo in equation:

1/λ = RZ^2(1/n1^2 - 1/n2^2)


Z=atomic number, which is 1 for hydrogen.
