Third-order reaction Definition & Meaning - Merriam-Webster

WebThe meaning of THIRD-ORDER REACTION is a chemical reaction in which the rate of reaction is proportional to the concentration of each of three reacting molecules. WebThe reaction is a third-order reaction. Units of rate constant for ‘n th ’ order reaction = M (1-n) s-1. Therefore, units of rate constant for the third-order reaction = M (1-3) s-1 = M-2 s-1 = L 2 mol-2 s-1. Example 2.
