Energetics (Thermochemistry) | Numericals & PYQs | NEET 2026 | Neeti Mishra | Dr VA-NEE-NI



Energetics (Thermochemistry) is one of the most numerical-heavy and repeatedly tested chapters in NEET Physical Chemistry. If fundamentals are weak, students lose easy marks due to sign errors, unit confusion, and incorrect application of formulas.

In this NEET 2026 lecture, Neeti Mishra Ma’am explains Thermochemistry from basics to NEET level, with strong focus on numericals, PYQs, and exam-oriented problem solving.

This lecture is ideal for students who:
• Get confused between different enthalpy terms
• Make mistakes in numerical calculations
• Memorise formulas but fail to apply them
• Want clarity on NEET PYQ patterns

Topics covered in this session:
• System, surroundings, and types of processes
• Enthalpy change and sign conventions
• Standard enthalpy of formation, combustion, and reaction
• Hess’s Law and its applications
• Bond enthalpy and energy calculations
• Numerical problem solving based on NEET pattern
• Previous Year Questions from NEET

This lecture is part of Dr VA-NEE-NI NEET Excellence, a joint academic venture by three experienced educators — Dr Vani Sood (Biology), Neeti Mishra (Chemistry), and Nikita Jain (Physics) — coming together to deliver free, high-quality NEET preparation on YouTube.

Dr Vani Sood is Ex-HOD at Vedantu, a core academic member at Vedantu, and a founding educator of Biotonic, one of India’s largest NEET Biology platforms.
Neeti Mishra, M.Pharm (GATE qualified), has 12+ years of experience teaching Chemistry at Aakash, Allen, and Physics Wallah, and has educated 10,000+ NEET aspirants.
Nikita Jain, B.Tech & M.Tech, has 12+ years of experience across Career Point, Aakash, Physics Wallah, and Unacademy, known for practical, real-life Physics teaching with results in NEET, JEE, and Olympiads.

On this channel, you’ll get:
• Free NEET classes
• NCERT-aligned concept building
• MCQs and PYQs
• One-shots and revision series
• Strategy and planning videos for NEET 2026, 2027 & 2028

Three teachers. One NEET direction.
