Web21 nov. 2024 · Rate of reaction measures the speed at which the reactants are converted to the products in a chemical reaction. For a reaction that occurs rapidly, the rate of reaction is high. Conversely, for a reaction that occurs slowly, the rate of reaction is low. WebSo this question gives us a table and wants us to find the order of the reaction and then the rate law and the value of the rate constant K. And so we know that the reaction is first order. And the reason we know that its first order is because when you double the concentration, you double the rate which defines the first order reaction.
