NEET 2016 Chemistry Equilibrium Questions
Use this page to connect the official 2016 paper with current Chemistry practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.
What to master
chemical equilibrium, acids, bases, buffers, solubility and ionic equilibria.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 3/5

- A. 1.70
- B. 3.70
- C. 4.00
- D. 5.70
Example 3 · difficulty 2/5
In the Haber process, N₂(g) + 3H₂(g) ⇌ 2NH₃(g), ΔH = −92 kJ mol⁻¹. Which of the following changes increases the equilibrium yield of NH₃?
- A. Raising the temperature at constant pressure
- B. Decreasing the total pressure
- C. Continuously liquefying and removing NH₃ as it forms
- D. Adding an inert gas at constant volume
The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions
Are these official NEET 2016 Chemistry Equilibrium PYQs?
No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.
How should I use the NEET 2016 paper?
Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
