Expected Weightage

The Common University Entrance Test (CUET) for Chemistry has included questions from the Equilibrium chapter consistently over the past few years. Below is an analysis of the marking pattern and chapter-wise weightage for Equilibrium in CUET (UG) based on available data.

1. Equilibrium Chapter Weightage (2022-2024)

• 2022 (First Edition):

• Total Questions: ~5-6 (out of 50 in Chemistry)

• Marks Allocated: ~10-12 (5 MCQs × 2 marks each)

• Topics Covered:

  • Chemical Equilibrium (Le Chatelier’s Principle, Kc Kp)
  • Ionic Equilibrium (pH, Buffer, Solubility Product)

• 2023:

• Total Questions: ~4-5

• Marks Allocated: ~8-10

• Key Topics:

  • Acid-Base Equilibrium (pH calculations, Henderson Equation)
  • Solubility Equilibria (Ksp)

• 2024 (Expected):

• Similar weightage (~10-12 marks)

• Focus areas: Buffer Solutions, Common Ion Effect, Relation between Kp Kc

2. Topic-wise Breakdown (Most Important)

3. Marking Scheme

• Correct Answer: +5 (if normalized) or +4 (raw)
• Incorrect Answer: -1 (negative marking in some sections)
• Unattempted: 0

4. Key Takeaways for Preparation

High Weightage Topics: - Le Chatelier’s Principle (Industrial applications) - pH Buffer Solutions (Numericals) - Relation between Kp, Kc, and Ksp

Practice Areas: - Equilibrium constant expressions - Calculations involving Henderson-Hasselbalch equation - Solubility product (Ksp) problems

Avoid: Overemphasis on theoretical definitions (CUET focuses more on application-based questions).

5. Previous Year Trends

• 2022: More conceptual (Le Chatelier’s Principle)
• 2023: More numerical (pH, Ksp calculations)
• 2024: Likely a mix of both

Conclusion

• Equilibrium carries ~20% weightage in Chemistry.
• Focus on numerical problems (pH, Kc/Kp, Ksp) and conceptual clarity.
• Revise NCERT thoroughly (most questions are NCERT-based).
