Rate of formation or disappearance of an optically active substance is monitored by:
Correct answer: D. Optical rotation
- A. Dilatometry
- B. Refractrometry
- C. Spectrometry
- D. Optical rotation
Explanation
Option d is the correct option. Optical rotation is the specific property of chiral (optically active) substances to rotate the plane of polarized light. It is used to quantify the concentration and specific rotation of optically active compounds, making it the appropriate method for monitoring their formation or disappearance.

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.
