How may reaction rates be measured
WebThe overall order of reaction is 2 - found by adding up the individual orders. Note: Where the order is 1 with respect to one of the reactants, the "1" isn't written into the equation. [A] means [A] 1. Example 2: This reaction is zero order with respect to A because the concentration of A doesn't affect the rate of the reaction. WebApr 12, 2024 · The atmospheric fate of 1,3-dioxolane is assessed by measuring the OH and Cl initiated gas-phase oxidation kinetics, and exploring their mechanistic pathways. Absolute OH reaction rate coefficient of 1,3-dioxolane using laser photolysis-laser induced fluorescence technique is found to be (1.27 ± 0.03) × 10–11 cm3 molecule−1 s−1 at 298 ± …
