Answer:
Explanation:
R = Rydberg constant =
= Principal quantum number of an energy level = 2
= Principal quantum number of an energy level for the atomic electron transition = 4
Wavelength is given by the Rydberg formula
The wavelength of the light emitted is .
A negative G indicates that there is more free energy in the reactants, or beginning state than in the products, or final state.
Exergonic reactions, which can take place without the supply of energy, are also known as spontaneous reactions.
Not all Gibbs's free energy is bad. Gibbs's free energy is negative for spontaneous reactions at a given temperature and positive for non-spontaneous reactions.
A spontaneous reaction is one that happens under specific circumstances without the addition of energy or outside influence. Since spontaneous reactions can happen rapidly or over the course of several days, months, or years, reaction spontaneity is independent of reaction rate.
