Spectrometry is used when reactants and products absorb?
Correct answer: D. All of these
- A. Ultraviolet radiation
- B. Visible radiation
- C. Infrared radiation
- D. All of these
Explanation
Spectrometry is a versatile analytical method that measures the absorption of electromagnetic radiation by reactants and products. This absorption can occur across various regions of the spectrum, including ultraviolet, visible, and infrared radiation. Therefore, the correct answer is 'All of these,' as it encompasses all the types of radiation listed in the options. The other options, listing individual types of radiation, are incorrect because they do not account for the full range of electromagnetic radiation utilized in spectrometry.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
