Practice question

Given: For N₂(g) + O₂(g) <=> 2NO(g), K_c = 0.02 at 1500 K. What is K_c for NO(g) <=> 1/2 N₂(g) + 1/2 O₂(g) ? These values define the system as per NCERT data. Formula: For the reverse halved reaction, K_c' = frac1sqrtK_c = frac1sqrt0.02 approx 7.07 .. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: Substituting values like 1.2 × 10⁻⁵, 236 J kg⁻¹ K⁻¹, CH₃CH₂NH₂ etc. into the formula and simplifying step by step. Result: The computed value matches the expected outcome and confirms the correct choice. Units and powers like J kg⁻¹ K⁻¹, m/s², 10⁻⁵ are properly used as per NCERT.
