The rate law describes how the rate of a reaction relates to the rate constant and the concentration of reactants when raised to appropriate powers. Reaction order is the power to which the concentration is raised in the rate law. Both the rate law and the order must be determined experimentally.

Likewise, the rate of a chemical reaction is a measure of how much reactant is consumed, or how much product is produced, by the reaction in a given amount of time. The rate of reaction is the change in the amount of a reactant or product per unit time. This means that the rate of change of [N 2 O 5] and [NO 2] must be divided by its stoichiometric coefficient to obtain equivalent expressions for the reaction rate. For example, because NO 2 is produced at four times the rate of O 2, the rate of production of NO 2 is divided by 4. The reaction rate expressions are as follows: At a particular temperature, the value of k, the specific rate constant for the production of KI 3 in this reaction, is equal to 0.299, k = 0.299. so at this temperature: rate = 0.299[C 2 H 4 Br 2][KI] Since the rate of this reaction refers to the production of products, the rate will be positive. The average rate of reaction, as the name suggests, is an average rate, obtained by taking the change in concentration over a time period, for example: -0.3 M / 15 minutes. This is an approximation of the reaction rate in the interval; it does not necessarily mean that the reaction has this specific rate throughout the time interval or even at any instant during that time. The rate law describes how the rate of a reaction relates to the rate constant and the concentration of reactants when raised to appropriate powers. Reaction order is the power to which the concentration is raised in the rate law. Both the rate law and the order must be determined experimentally. - The rate of a chemical reaction is defined as the change in the concentration of a reactant or a product over the change in time, and concentration is in moles per liter, or molar, and time is in seconds. So we express the rate of a chemical reaction in molar per second.

For most reactions, the rate decreases as the reaction proceeds. Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts of

At a particular temperature, the value of k, the specific rate constant for the production of KI 3 in this reaction, is equal to 0.299, k = 0.299. so at this temperature: rate = 0.299[C 2 H 4 Br 2][KI] Since the rate of this reaction refers to the production of products, the rate will be positive.

Chemical reactions proceed at different rates. The factors that affect reaction rates are: surface area of a solid reactant; concentration or pressure of a reactant   This rate constant converts chemical concentrations into reaction rates. Thus, in the above example, the rate of production C = k [A] [B], where k is the rate.
