Reaction Rate: The concept of reaction rate is fundamental in chemical kinetics. It is defined as the rate at which the concentrations of reactants decrease or the concentrations of products increase over time. This rate can be measured and expressed in terms of the change in concentration of a reactant or product per unit time, typically in units of molarity per second (M/s).

Measuring Reaction Rates:

Measuring the rate of a chemical reaction involves monitoring changes in the concentration of reactants or products over time. This can be done through various methods, such as:

Concentration Changes Over Time:

- Monitoring the decrease in concentration of reactants or the increase in concentration of products as the reaction progresses. Techniques like spectroscopy, titration, or conductivity measurements can be employed depending on the nature of the reactants and products.

Rate Units:

- Reaction rates are commonly expressed in molarity per second (M/s), indicating how fast the concentration of a substance is changing in the reaction mixture. The units can vary depending on the specific reaction and the way the rate is being measured.
