Practice question

Given: A reaction follows the rate law Rate = k[A][B] . If k = 0.5 L mol^{-1 s^{-1, [A] = 0.2 M, and [B] = 0.3 M, what is the initial rate in mol L^{-1 s^{-1 ? These values define the system as per NCERT data. Formula: Rate = k[A][B] = 0.5 × 0.2 × 0.3 = 0.03 mol L^{-1 s^{-1 .. This is standard NCERT relation. Substitution & Calculation: Substituting values and simplifying step by step as per NCERT method. Result: The computed value matches expected outcome and confirms correct choice as per NCERT.
