📖 NCERT CHAPTER COVERED:
Class 12 Chemistry - Chapter 4: Chemical Kinetics (Latest NCERT Syllabus 2025-26)

🔥 WHY THIS VIDEO?
Chemical Kinetics is a high-scoring chapter with guaranteed numericals in every exam. Students often struggle with order vs molecularity, integrated rate equations, and half-life calculations. We've simplified everything with clear graphs and step-by-step problem-solving methods perfect for scoring maximum marks.

💡 IMPORTANT FORMULAS COVERED:
Rate of reaction: r = -Δ[R]/Δt = +Δ[P]/Δt
Rate law: Rate = k[A]^m[B]^n
Units of k for different orders
Zero order: [R] = [R]₀ - kt, t₁/₂ = [R]₀/2k
First order: ln[R] = ln[R]₀ - kt, t₁/₂ = 0.693/k
Second order: 1/[R] = 1/[R]₀ + kt, t₁/₂ = 1/k[R]₀
Pseudo first order: Rate = k'[A]
Arrhenius equation: k = Ae^(-Ea/RT)
log(k₂/k₁) = (Ea/2.303R)(1/T₁ - 1/T₂)
Activation energy: Ea = RT ln(A/k)
For parallel reactions: k = k₁ + k₂
For consecutive reactions: Use steady state approximation

📊 CHAPTER WEIGHTAGE:
Board Exam: 5-7 marks (High!)
JEE Main: 2-3 questions
NEET: 1-2 questions
This is a HIGH WEIGHTAGE chapter - essential for all exams!

🎓 KEY CONCEPTS EXPLAINED:
Difference between rate and rate constant
Order vs molecularity (key difference!)
Why order can be fractional but molecularity cannot
Zero order reactions (surface catalyzed reactions)
First order reactions (radioactive decay)
Pseudo first order reactions (hydrolysis examples)
Half-life dependence on initial concentration
Collision theory and effective collisions
Activation energy concept and diagram
Why catalysts lower activation energy
Temperature coefficient (rate doubles every 10°C)
Threshold energy vs activation energy
Arrhenius plot (log k vs 1/T)
