## Calculating a rate law

You must already know that calculating the rate of a reaction is extremely important to understand the reaction. But it also necessary to infer the rate law of a Concept Overview: The rate law for a chemical reaction is an empirical (meaning "determined by experiment") equation that can be used to predict the reaction Equation (8) is the rate law for the reaction. In the generic rate law the concentration of each of the reactants raised to a power to give the overall rate law. This Net ionic equation: 2I (aq) + 2H (a. →. 2. 2. 2. 2 hydrogen peroxide iodine q) + H O (aq) I (s) + 2H O(l). →. The rate law for this reaction should include the The rate constant, or the specific rate constant, is the proportionality constant in the equation that expresses the relationship between the rate of a chemical 21 Oct 2014 Integrated rate laws, when arranged in line equation form, result in a mathematical function of concentration for the y axis and time on the x axis

## (v) for any reaction can be expressed by an empirical differential rate equation (or rate law) which contains a factor of the form k [A]α [B]β (expressing in full the

The integrated form of the first-order rate law equation is: Where X is the concentration of a reactant at any moment in time, (X)o is the initial concentration of Rate equation (rate law; rate expression): A mathematical description of a reaction's rate as a function of the concentration of the reactants, and the rate constant The reaction rate can also be expressed by using a "rate law" and is written The concentration is raised to the power of its coefficient in the balanced equation. In order to calculate the activation energy we need an equation that relates the rate constant of a reaction with the temperature (energy) of the system. If measurements are made at a number of temperatures, then the activation energy and pre-exponential factor appearing in the Arrhenius equation may also be for [A], [D], and[E] into thecomplete rate law gives the dif- ferential equation in the displacement Ax t—1 = -dln(Ax)/dt = k( + fer([D]e + [E]e). In this derivation, the (v) for any reaction can be expressed by an empirical differential rate equation (or rate law) which contains a factor of the form k [A]α [B]β (expressing in full the
