4. Solutions A and B are both clear and colorless. When Solution A is mixed with Solution B, the temperature of the mixture increases and a yellow precipitate is observed. What can be concluded from these observations? (A) The reaction is thermodynamically favored (spontane- ous) at all temperatures. (B) The reaction is thermodynamically favored (spontane- ous) only at high temperatures. (C) The reaction is thermodynamically favored (spontane- ous) only at low temperatures. (D) The reaction is not thermodynamically favored (sponta- neous) at any temperature.

UV Visible Spectroscopy

Spectroscopy refers to the absorption or emission of light or other radiations by matter. When a substance or chemical absorbs light or radiation, they reach an excited state followed by de-excitation or emission of the light or radiation forming distinct spectra. UV-visible spectroscopy or  ultraviolet-visible refers to the absorption and emission in the ultraviolet and visible regions of the electromagnetic spectrum.
