UNIT 07 : REACTION KINETICS

Reaction Kinetics is a core chapter in MDCAT Chemistry, sitting within the 25% Chemistry allocation of your 45-question paper.

What this chapter covers:

• Definition of chemical kinetics
• Rate of reaction and rate equation
• Factors affecting rate of reaction
• Order of reaction and rate law
• Activation energy and activated complex
• Role of the rate constant in reaction rate

This chapter blends conceptual understanding with numerical problem-solving, covering everything from definitions and mechanisms to order determination and Arrhenius-based calculations. Given this mix of qualitative reasoning and quantitative work, it falls across the easy-to-moderate range with pockets of genuine difficulty, matching PMDC’s overall 15% easy, 70% moderate, 15% difficult split.

Why this practice set helps:

• Covers every subtopic the PMDC curriculum identifies, plus the supporting concepts textbooks present alongside them
• Every question includes a full explanation of why the correct answer is right and why each other option is wrong
• Built to help you learn faster than passive reading, with nothing the exam may draw from left untouched

Work through this set attentively, and you build both the conceptual clarity and calculation precision this chapter demands.
