It covers the most important and frequently asked numerical problems from the Chemical Kinetics chapter. Key topics covered in the video include: Rate of Reaction: Calculating average rate, rate of disappearance of reactants, and rate of production of products [02:48]. First-Order Reactions: Using the integrated rate equation to find time, rate constants, and initial concentrations [10:33]. Half-Life Calculations: Problems involving t 1/2 ​ and its relationship with the rate constant k [13:02]. Showing Relationships: Proving that the time for 99% completion is a specific multiple of half-life (common 3-5 mark questions) [22:33]. Arrhenius Equation: Solving for Activation Energy and understanding how the rate constant changes with temperature [30:16]. Pre-exponential Factor: Comparing given equations with the standard Arrhenius form to find 'A' [34:23].
