← Initial rates are measured for a reaction of A and B. Run 1: [A] = 0.13 mol/L, [B] = 0.19 mol/L, rate 4.6 × 10⁻⁵ mol L⁻¹ s⁻¹. Run 2: [A] = 0.39 mol/L, [B] = 0.19 mol/L, rate 1.38 × 10⁻⁴ mol L⁻¹ s⁻¹. Run 3: [A] = 0.39 mol/L, [B] = 0.57 mol/L, rate 1.242 × 10⁻³ mol L⁻¹ s⁻¹. What is the rate law?Assertion (A): The molecularity of a complex reaction cannot be stated as one number. Reason (R): Molecularity is found by experiment, from the rate law of the reaction. →
