Expected Weightage

The Common University Entrance Test (CUET) for Chemistry, particularly the Chemical Kinetics section, has shown specific trends in marking patterns and chapter-wise weightage over the last three years (2022-2024). Below is a detailed analysis based on available data and trends:

1. Overall Weightage of Chemical Kinetics in CUET Chemistry

• Average Marks Allocated: 4-6 marks (out of 50 in Chemistry section).
• Frequency: Typically 2-3 questions per year (MCQs).
• Difficulty Level: Mostly moderate , with 1-2 conceptual/tricky questions.

2. Chapter-wise Weightage Trends (2022-2024)

Chemical Kinetics is divided into subtopics, and CUET tends to focus on the following areas:

3. Year-wise Breakdown

2024 (Expected Trend)

• Emphasis on numerical problems (rate law, half-life calculations).
• 1 question likely from graph interpretation (e.g., first-order reaction plots).

2023

• 2 MCQs on rate law (experimental determination of order).
• 1 MCQ on Arrhenius equation (log k vs. 1/T graph).

2022 (First CUET Edition)

• 1 MCQ on units of rate constant for zero/first-order reactions.
• 1 MCQ on half-life of a first-order reaction.

4. Key Takeaways for Preparation

• High-Yield Topics:
• Rate law order determination (practical-based questions).
• First-order reactions (half-life, integrated rate equations).
• Arrhenius equation (graphical interpretation).
• Low-Yield Topics:
• Collision theory (rarely asked).
• Complex mechanisms (e.g., pseudo-first-order).

5. Recommended Resources

• NCERT Class 12 (Ch. 4): Covers 90% of CUET syllabus.
• Practice Questions: Focus on numericals from rate law and half-life.

Conclusion

Chemical Kinetics is a moderately important chapter in CUET Chemistry, contributing ~8-12% of the total marks. Prioritize rate laws, order determination, and Arrhenius equation for scoring well.
