The reaction rate is the speed at which reactants turn into products, measured by observing the decrease in reactants or increase in products over time. Methods like tracking the mass of reactants or monitoring the volume of gas produced show that the reaction rate usually decreases as the reaction advances.
Insights
- Reaction rate is how quickly reactants turn into products in a chemical reaction, measured by observing reactant decrease or product increase over time.
- Methods like tracking mass loss of reactants or gas volume produced, as seen in the marble chips and hydrochloric acid reaction, demonstrate that reaction rates usually decrease as the reaction continues.

Recent questions
What is reaction rate?
The reaction rate is the speed at which reactants transform into products in a chemical reaction. It can be measured by observing the decrease in reactants or the increase in products over time.
How can reaction rate be measured?
Reaction rate can be measured by tracking the decrease in mass of reactants or monitoring the volume of gas produced during a chemical reaction.
What are examples of reactants used to measure reaction rate?
Examples of reactants used to measure reaction rate include marble chips (calcium carbonate) and hydrochloric acid, which show a decrease in mass as the reaction progresses.
What does the rate of reaction typically do as the reaction progresses?
The rate of reaction typically slows down as the reaction progresses, as observed in the decrease in mass of reactants or the volume of gas produced over time.
How does the volume of gas produced relate to reaction rate?
The volume of gas produced during a chemical reaction can be used to measure reaction rate, showing an increase in gas volume as the reaction proceeds and a decrease in rate over time.

Chemical reaction rate measurement methods explained
- Reaction rate is defined as the speed at which reactants transform into products in a chemical reaction. It can be measured by observing the decrease in reactants or the increase in products over time.
- To measure reaction rate, one can track the decrease in mass of reactants, like in the reaction between marble chips (calcium carbonate) and hydrochloric acid, or monitor the volume of gas produced, such as carbon dioxide. Both methods show that the rate of reaction typically slows down as the reaction progresses.
