Easiest Chemical Kinetic Notes12th class Cbse

"Chemical Kinetics" in Class 12 Chemistry


Introduction:


  • Chemical kinetics is the branch of chemistry that deals with the study of the rates of chemical reactions and the factors that affect these rates.
  • Understanding chemical kinetics is important in various fields, including industry, medicine, and environmental science.

Rate of Reaction:

  • The rate of reaction is the change in concentration of reactants or products per unit time.
  • The rate of reaction can be determined by measuring the change in concentration of reactants or products over time.

Factors Affecting Rate of Reaction:

  • The rate of reaction can be affected by several factors, including temperature, concentration, surface area, and the presence of a catalyst.
  • Increasing the temperature, concentration, and surface area of the reactants generally increases the rate of reaction.
  • Catalysts are substances that increase the rate of reaction without being consumed in the reaction.

Order of Reaction:

  • The order of reaction is the exponent of the concentration of a reactant in the rate law equation.
  • The rate law equation is an equation that relates the rate of reaction to the concentrations of the reactants.
  • The order of reaction can be determined experimentally.

Integrated Rate Laws:

  • Integrated rate laws are equations that relate the concentration of a reactant or product to time.
  • The integrated rate laws can be used to determine the order of reaction and the rate constant.

Half-Life:

  • The half-life of a reaction is the time it takes for half of the reactants to be consumed or for half of the products to be formed.
  • The half-life of a reaction can be used to determine the rate constant and the order of reaction.

Activation Energy:

  • Activation energy is the minimum amount of energy required for a reaction to occur.
  • Increasing the temperature generally increases the reaction rate by providing more energy to overcome the activation energy barrier.

Catalysis:

  • Catalysts are substances that increase the rate of reaction without being consumed in the reaction.
  • Catalysts work by lowering the activation energy required for the reaction to occur.
  • Catalysts can be homogeneous or heterogeneous, depending on whether they are in the same phase as the reactants or in a different phase.

In conclusion, the chapter "Chemical Kinetics" in Class 12 Chemistry covers important concepts related to the rates of chemical reactions, factors affecting the rate of reaction, order of reaction, integrated rate laws, half-life, activation energy, and catalysis. Understanding these concepts is important in various fields of chemistry and related sciences, including industrial processes, environmental science, and medicine. Mastery of this chapter can also be helpful for students who plan to pursue further studies in chemistry or related fields
