FAQs on Short Tricks: Chemical Kinetics Video Lecture - Chemistry Class 12 - NEET

1. What is chemical kinetics?
Ans. Chemical kinetics is the branch of chemistry that studies the rate at which chemical reactions occur and the factors that influence this rate.
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 time. This can be done by monitoring the appearance or disappearance of a characteristic property, such as color or pressure.
3. 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, presence of catalysts, surface area, and pressure (for gases). These factors can either increase or decrease the rate of the reaction.
4. What is a catalyst and how does it affect the rate of a chemical reaction?
Ans. A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It works by providing an alternative reaction pathway with a lower activation energy, allowing the reaction to proceed faster. Catalysts can significantly speed up reactions and are often used in industrial processes.
5. How can the rate of a chemical reaction be expressed mathematically?
Ans. The rate of a chemical reaction can be expressed mathematically using the rate equation, which relates the rate of the reaction to the concentrations of the reactants. The rate equation is determined experimentally and typically includes the reaction order and rate constant.
