Practice question

Given: A zero-order reaction has a half-life of 25 minutes with an initial concentration of 0.25 M. What is the rate constant in mol L^{-1 min^{-1 ? These values define the system as per NCERT data. Formula: t_{1/2 = frac[R]_02k, 25 = 0.25/2k, k = 0.25/50 = 0.005 .. 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.
