17.Radiations are absorbed in
Correct answer: A. (a) Spectrophotometer method
- A. (a) Spectrophotometer method
- B. (e) Optical relation method
- C. (b) Dilatometric method
- D. (d) Refractometric method
Explanation
The correct answer to the question "Radiations are absorbed in" is:(a) Spectrophotometer methodHere's why the other options are incorrect:(b) Dilatometric method: This method measures changes in the dimensions of a material due to thermal or chemical expansion/contraction. It doesn't involve absorption of radiation.(c) Optical relation method: This is not a well-defined term in standard chemical or analytical methods. It's unclear what kind of "radiations" this method would involve absorbing.(d) Refractometric method: This method measures the refractive index of a material, which relates to how light bends when passing through it. While refractometers use light sources, they don't involve the absorption of radiation by the analyte.

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.
