Original practice preview

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

Example 1 · difficulty 3/5

For the reaction A + B → products, the following initial rate data were obtained: Experiment 1: [A] = 0.1 mol L⁻¹, [B] = 0.1 mol L⁻¹, rate = 2.0 × 10⁻³ mol L⁻¹ s⁻¹; Experiment 2: [A] = 0.2 mol L⁻¹, [B] = 0.1 mol L⁻¹, rate = 4.0 × 10⁻³ mol L⁻¹ s⁻¹; Experiment 3: [A] = 0.2 mol L⁻¹, [B] = 0.2 mol L⁻¹, rate = 1.6 × 10⁻² mol L⁻¹ s⁻¹. The overall order of the reaction is:

A. 1
B. 2
C. 1.5
D. 3

Example 2 · difficulty 3/5

The rate constant of a reaction doubles when the temperature is raised from 300 K to 310 K. The activation energy of the reaction is approximately (log 2 = 0.301, R = 8.314 J K⁻¹ mol⁻¹):

A. 53.6 kJ mol⁻¹
B. 26.8 kJ mol⁻¹
C. 5.36 kJ mol⁻¹
D. 107.2 kJ mol⁻¹

Example 3 · difficulty 2/5

For a first-order reaction, the time required for 99.9% completion is approximately how many times its half-life?

A. 5
B. 10
C. 100
D. 2

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 2017 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 2017 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.
