Which of the following statements most accurately describes UV-Vis spectroscopy?
  • a)
    Inside a spectrophotometer, the beam is split into two where one beam is used as a reference and the other beam is used to cause interference with the reference.
  • b)
    The absorbance of a compound is proportional to the concentration of the sample and inversely proportional to the path length according to Beer’s Law.
  • c)
    UV-Vis spectroscopy can be used to measure the kinetics or the rate constant of a reaction.
  • d)
    For molecules containing π or non-bonding electrons, the larger the HOMO-LUMO gap, the longer the wavelength the compound absorbs.
Correct answer is option 'C'. Can you explain this answer?

  • According to Beer’s law, the absorbance of a compound is proportional to the concentration of the sample and also proportional to the path length.
  • According to Beer’s law, the absorbance of a compound is proportional to the concentration of the sample and also proportional to the path length.
  • For molecules containing π or non-bonding electrons, the more easily excited the electrons or the smaller the HOMO-LUMO gap, the longer the wavelength it can absorb.
  • UV-Vis spectroscopy indeed can be used to measure the kinetics or the rate constant of a reaction, provided a reagent or product shows distinctive absorbance in the UV or visible spectral region.
