For 2SO₃(g) 2SO₂(g) + O₂(g), adding an inert gas at constant pressure will:
Given: For 2SO₃(g) 2SOâ‚‚(g) + Oâ‚‚(g), adding an inert gas at constant pressure will: These values define the system as per NCERT data. Formula: Δ n = (2 + 1) - 2 = 1. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: At constant pressure, adding an inert gas increases volume, shifting to products (more moles). Result: The computed value matches the expected outcome and confirms the correct choice. Units and powers like J kgâ»Â¹ Kâ»Â¹, m/s², 10â»âµ are properly used as per NCERT.
