FAQs on Quick Revision: Chemical Kinetics - Physical Chemistry for NEET

1. What is chemical kinetics?
Ans. Chemical kinetics is the branch of chemistry that studies the rates of chemical reactions and the factors that influence them. It involves understanding the speed at which reactants are consumed and products are formed during a chemical reaction.
2. What are the factors that affect the rate of a chemical reaction?
Ans. Several factors can affect the rate of a chemical reaction, including temperature, concentration of reactants, surface area, catalysts, and the presence of inhibitors. These factors can either increase or decrease the rate of a reaction.
3. 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 reactant molecules, increasing their kinetic energy and the frequency of successful collisions between them. As a result, more reactant molecules possess the necessary activation energy to overcome the energy barrier and form products.
4. What is the role of catalysts in chemical reactions?
Ans. Catalysts are substances that can speed up the rate of a chemical reaction without being consumed in the process. They achieve this by providing an alternative reaction pathway with lower activation energy. Catalysts work by increasing the frequency of successful collisions between reactant molecules or by stabilizing transition states, making the reaction more favorable.
5. How does concentration affect the rate of a chemical reaction?
Ans. Increasing the concentration of reactants generally increases the rate of a chemical reaction. This is because a higher concentration means more reactant molecules are present, leading to an increased frequency of collisions between them. With more collisions, there is a higher probability of successful collisions that result in the formation of products.
