Practice question

Given: A reaction follows Rate = k[A][B]² with k = 0.1 L² mol^{-2 s^{-1, [A] = 0.2 M, and [B] = 0.4 M. What is the rate in mol L^{-1 s^{-1 ? Formula: Rate = k[A][B]² = 0.1 × 0.2 × (0.4)² = 0.1 × 0.2 × 0.16 = 0.0032 .. Substitution: Substituting given values into formula as per NCERT 2026-27 method. Calculation: Simplifying step by step with proper SI units like m/s², J kg⁻¹ K⁻¹, 10⁻⁵, A m⁻¹ etc. Final Result: The computed value matches expected outcome and confirms correct choice as per latest NCERT 2026-27.
