Concept:Le Chatelier's Principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change.
Formula:$$ \text{Equilibrium Shift Factors: } P, T, C $$
Solution:- Changing the Concentration of reactants or products shifts the reaction to consume the excess.
- Changing Pressure (or Volume) affects reactions involving gases with \( \Delta n \neq 0 \).
- Changing Temperature alters the equilibrium constant \( K_c \) itself depending on whether it is exothermic or endothermic.
- Therefore, all three factors actively affect reversible chemical reactions.
Why other options are incorrect:Options A, B, and C are individually correct but incomplete. D is the comprehensive answer.
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.
