Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Takes place from left to right as given in chemical equation
Concept:

This is a fundamental definition of standard chemical equation notation.

Solution:

  • By universal IUPAC convention, chemical equations are written with original Reactants on the left side and newly formed Products on the right side.


  • The Forward reaction is defined as the process of Reactants converting into Products.


  • Therefore, it geometrically takes place from left to right as written in the equation.


Why other options are incorrect:

The forward reaction is actually at its fastest at the very beginning (eliminating A and C). Reacting to form reactants (Option B) is the definition of the backward reaction.

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.
