Reaction rates year 10

WebThe rate of a reaction can be expressed by any one of the reactants or products in the reaction. There are a couple of rules to writing rate expressions: Expressions for reactants are given a negative sign. This is because the reactant is being used up or decreasing. Expressions for products are positive. This is because they are increasing. WebThe reaction rate is the speed with which the products are produced and the reactants are consumed in a specific reaction. It is usually discussed in terms of the rate at which one component of the mixture is used up or formed. A rate equation gives the relationship between the reaction rate and the concentration of the reactants.

12.2 Factors Affecting Reaction Rates Chemistry - Lumen Learning

WebA general rule is that a 10°C temperature increase can double a reaction rate. It turns out that the increase in the reaction rate is mainly a function of the more intense collisions. Increased collision frequency is not as significant a factor. Nature of Reactants. Individual properties of substances also affect reaction rates.
