What does the word rate mean in everyday life and what do chemists mean by reaction rate?

In everyday life, the Word "rate" often refers to the speed or frequency at which something occurs, such as a heart rate or interest rate. In chemistry, "reaction rate" specifically describes how quickly a chemical reaction takes place, typically measured by the change in concentration of reactants or products over time. Factors such as temperature, concentration, and catalysts can influence this rate, determining how fast a reaction proceeds.
