FAQs on Chemical kinetics Practice set-5 (JAM) - Additional Documents & Tests for IIT JAM

1. What is the definition of chemical kinetics?
Ans. Chemical kinetics is the branch of physical chemistry that deals with the study of the rates of chemical reactions and the factors that influence these rates.
2. How is the rate of a chemical reaction determined?
Ans. The rate of a chemical reaction is determined by measuring the change in concentration of reactants or products over a specific period of time. This can be done by analyzing the reaction mixture using various techniques such as spectroscopy or titration.
3. What are the factors that can affect the rate of a chemical reaction?
Ans. The rate of a chemical reaction can be influenced by several factors including temperature, concentration of reactants, presence of catalysts, surface area of reactants, and the physical state of reactants (solid, liquid, or gas).
4. How does temperature affect the rate of a chemical reaction?
Ans. Increasing the temperature generally increases the rate of a chemical reaction. This is because higher temperatures provide more energy to the reacting particles, leading to more frequent and energetic collisions, which in turn increases the likelihood of successful collisions and reaction.
5. What is the role of catalysts in chemical reactions?
Ans. Catalysts are substances that can increase the rate of a chemical reaction without being consumed in the process. They work by providing an alternative reaction pathway with lower activation energy, allowing the reaction to occur more readily. Catalysts can significantly speed up reactions and are widely used in various industrial processes.
