Practice question

Given: For 2H₂O(g) <=> 2H₂(g) + O₂(g), decreasing volume will: These values define the system as per NCERT data. Formula: Δ n = (2 + 1) - 2 = 1. This is standard NCERT relation. Substitution & Calculation: Decreasing volume (increasing pressure) shifts to reactants (fewer moles). Result: The computed value matches expected outcome and confirms correct choice as per NCERT.
