Best NEET Mock Test for Chemical Thermodynamics 2025

Practice is crucial for NEET success, especially in Chemistry chapters like Chemical Thermodynamics. This mock test offers NEET 2025 aspirants 20 MCQs curated to reflect NTA’s latest exam pattern. Instant scoring and solution review empower you with detailed performance analytics for rapid improvement in both accuracy and speed.


Chemical Thermodynamics covers heat, work, internal energy, enthalpy, and entropy—core topics that often decide scores in competitive exams. Attempting this test ensures you confront real NEET difficulty, master thermodynamics laws, and understand applications relevant for both Class 11 and NEET Chemistry sections.


Why Master Chemical Thermodynamics for NEET?

Chemical Thermodynamics holds high weightage, often contributing 3-5 direct questions in NEET Chemistry annually. Questions commonly revolve around the first law, spontaneity (Gibbs free energy), entropy changes, and enthalpy calculations. Reinforcing your grip with accurate mock practice boosts memory retention and exam-time confidence.


Regular mock exposure helps you identify weak areas, manage time efficiently, and adapt to evolving NEET-style MCQs. Analytical skills in thermodynamics also strengthen problem-solving in related NCERT topics such as chemical equilibrium and kinetics.


NEET-Style Concept Conversions & Examples

Concept Formula/Relation Typical NEET Use
First Law of Thermodynamics ΔU = q + w Change in internal energy
Work (Isothermal, Ideal Gas) w = –nRT ln(Vf/Vi) Gas expansion/compression
Enthalpy Change ΔH = ΔU + ΔnRT Reactions involving gases
Gibbs Free Energy ΔG = ΔH – TΔS Spontaneity prediction
Entropy Change (Reversible) ΔS = qrev/T Phase, mixing, or gas expansion

Chemical Thermodynamics NEET Question Patterns

NEET questions from this chapter are application-oriented. Common question types include conceptual MCQs, numerical calculations of work or heat, and theory-based spontaneous process predictions. Solving similar mock papers boosts both formula recall and test endurance.


By taking this test, you familiarize yourself with NEET-level traps, such as changes in conditions (temperature, volume), making you less likely to fall for distractors. Remember, success in NEET depends on your comfort with time-bound practice as much as conceptual clarity.
