Select the chemical method used for the determination of the reaction rate:
Correct answer: D. Volumetric analysis
- A. Conductometry
- B. Polarimetry
- C. pH meter
- D. Volumetric analysis
Explanation
Volumetric analysis is specifically designed to measure concentration changes in a reaction over time, making it ideal for determining reaction rates. Unlike conductometry, which relates to ionic conductivity, polarimetry, which involves optical properties, and pH meters, which assess acidity levels, volumetric analysis provides a direct measure of how concentrations of reactants or products change, directly correlating to reaction rates.

About Rate of Reaction
Reaction rate measures the change in concentration of a reactant or product per unit time. Questions connect rate with concentration, temperature, pressure, surface area, catalysts and nature of reactants, and may involve rate laws, reaction order, activation energy and collision theory. Rate describes speed, whereas equilibrium describes the final balance of opposing reactions.
