<span>Enthalpy is regarding the amount of heat that is given off or taken in during the process of a reaction, while entropy is about the disorderliness of a reaction.
Both are related in the equation ∆G=∆H-T∆S, where ∆G is the Gibbs free energy. So we can say that a reaction is both enthalpy and entropy driven. It's like, both of them are interlinked with each other. </span>
Answer: option A. the colors absorbed when an element gains energy.
Justification:
The electromagnetic waves, visible light included, consists of a gamma of waves with different frequencies and wavelengths.
The visible light can be decomposed in a set of series of lines of light with different frequencies and that decomposition is what a spectrum of light is. Each series correspond to a color.
The atoms can absorb and emit photons. That is, atoms can absorb and release energy.
When the atom abosorbs a photon an electron gets excited ( the electron gains energy).
The light absorbed, then, corresponds to color absortion, and the spectrum of absortion is the colors absorbed by the atom when its electrons gain energy by the absortion of photons (light).
