### Top 10 Concepts Covered in Class 12 Chemistry Chapter 4 “Chemical Kinetics”

Here are the top 10 concepts covered in Class 12 Chemistry Chapter 4 “Chemical Kinetics”:

**Rate of Reaction**: The change in concentration of reactants or products per unit time.**Factors Affecting Reaction Rates**: The influence of nature and state of reactants, concentration, temperature, and catalysts on the rate of reactions.**Rate Law and Rate Constant**: The mathematical relationship between the reaction rate and the molar concentration of reactants, and the constant of proportionality in this equation.**Order of Reaction**: The sum of the powers of the concentration terms in the rate equation.**Molecularity of Reaction**: The number of reacting species that collide simultaneously to bring about a chemical change.**Integrated Rate Equations**: Mathematical expressions that relate the concentration of reactants to time for zero, first, and second-order reactions.**Half-Life of Reactions**: The time required for the concentration of a reactant to reduce to half its initial value.**Arrhenius Equation**: The equation that shows the dependence of the rate constant on temperature and activation energy.**Activation Energy**: The minimum energy required for a reaction to occur.**Catalysis**: The process by which the rate of a chemical reaction is increased by a substance called a catalyst.

### Key Formulas to Remember for NCERT Class 12 Chemistry Chapter 4 “Chemical Kinetics”

**Rate of Reaction**:

Where ([A]) and ([B]) are the concentrations of the reactants and products, respectively, and (t) is time.

**Rate Law**:

Where (k) is the rate constant, ([A]) and ([B]) are the concentrations of reactants, and (m) and (n) are the orders of the reaction with respect to each reactant.

**Integrated Rate Law for First Order Reactions**:

Where ([A]) is the concentration of reactant at time (t), (k) is the rate constant, and ([A]_0) is the initial concentration.

**Half-Life for First Order Reactions**:

Where (t_{1/2}) is the half-life of the reaction and (k) is the rate constant.

**Arrhenius Equation**:

Where (k) is the rate constant, (A) is the pre-exponential factor, (E_a) is the activation energy, (R) is the gas constant, and (T) is the temperature in Kelvin.

**Second Order Reaction (for one reactant)**:

Where ([A]) is the concentration of reactant at time (t), (k) is the rate constant, and ([A]_0) is the initial concentration.

**Second Order Reaction (for two reactants)**:

Where ([A]) and ([B]) are the concentrations of the two reactants at time (t), (k) is the rate constant, and ([A]_0) and ([B]_0) are the initial concentrations.

### Common Mistakes to Avoid in NCERT Class 12 Chemistry Chapter 4 “Chemical Kinetics”

When studying NCERT Class 12 Chemistry Chapter 4 “Chemical Kinetics,” students should be mindful to avoid these common mistakes:

**Confusing Rate of Reaction with Rate Constant**: Remember that the rate of reaction varies with concentration, while the rate constant does not.**Incorrect Use of Rate Laws**: Ensure you apply the correct rate law for the order of the reaction and do not confuse the overall order with the order with respect to one reactant.**Misinterpreting Orders of Reactions**: The order of a reaction is determined experimentally and not from the stoichiometry of the reaction equation.**Overlooking Units**: Always check the units when calculating rate constants, as they change with the order of the reaction.**Neglecting Temperature’s Role**: Be aware of how temperature affects reaction rates and the Arrhenius equation’s parameters.**Mistakes in Half-Life Calculations**: For first-order reactions, the half-life is constant, but for other orders, it changes with concentration.**Misapplication of Arrhenius Equation**: Understand the significance of activation energy and the pre-exponential factor when using this equation.**Ignoring the Collision Theory**: Recognize the importance of the orientation and energy of colliding particles in determining reaction rates.**Errors in Integrated Rate Equations**: Use the correct form of the integrated rate equation based on the order of the reaction.**Assuming Instantaneous Equilibrium**: In reversible reactions, equilibrium is reached over time, and the rates of the forward and reverse reactions must be considered.
