Question

वैरीयस फिजिकल एंड केमिकल मेथड फॉर मेजरिंग रेट आफ रिएक्शन​

Answer 1

Answer:

Physical measurements can be performed on a system while it is reacting. These measurements have the advantage of not disturbing the system, and they can be taken during the reaction. Examples of these measurements are changes in volume, temperature, and absorption of a solution.

Chemical methods of measurement yield concentrations directly. A small sample is extracted from the reacting mixture, and the reaction is halted by dilution, cooling the mixture long enough to measure concentrations, or adding another reagent to stop the reaction.
