What to master

rate laws, order, integrated equations, half-life and activation energy.

Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 1/5

Powdered calcium carbonate reacts faster with acid than an equal mass of marble chips mainly because powder has:

A. A larger equilibrium constant
B. A different molar mass
C. A lower product concentration at equilibrium
D. Greater exposed surface area

Example 2 · difficulty 1/5

Raising temperature usually increases reaction rate because it increases:

A. The fraction of collisions with energy at least equal to activation energy
B. Only the number of product molecules at equilibrium
C. The activation energy itself
D. The stoichiometric coefficients

Example 3 · difficulty 1/5

Increasing the concentration of gaseous reactants at fixed temperature often speeds reaction because:

A. Every collision becomes perfectly oriented
B. Collisions occur more frequently per unit volume
C. Activation energy becomes zero
D. The balanced equation changes

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 2025 Chemistry Chemical Kinetics 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 2025 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.
