Concept:Collision theory dictates that for a reaction to occur, particles must collide with sufficient energy (activation energy) and proper spatial orientation.
Solution:- While orientation is crucial for complex molecules, the formation of a hydrogen molecule (\( \text{H}_{2} \)) from two hydrogen atoms is a unique exception.
- Hydrogen atoms possess a perfectly spherical (1s) electron cloud.
- Because they are completely spherically symmetrical, they look identical from every angle. Therefore, their collision does NOT require any specific orientation to be effective.
Why other options are incorrect:Options A, B, and C are true core postulates of standard collision theory (particles must collide, not all collisions work, and they need minimum energy).
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
