PowerPoint Presentation: The rate of reaction is proportional to the square of the concentration of A This means that if you doubled the concentration of A, the rate would go up 4 times (2 2). If you tripled the concentration of A, the rate would increase 9 times (3 2). Chemical Kinetics Rates of Reaction • Kinetic = movement or change • Chemical kinetics is the area of chemistry concerned with the speed, or rates, at which a chemical reaction occurs • Reaction rate is the change in the concentration of a reactant or a product with time (M/s) • Why reactions have such vastly different rates? Rate of reaction graph. Amount of product formed. Time. Reaction begins. rapidly. Slows down as time passes as reactants are used up. Stops after a certain time – graph levels out as one (or both) reactants have been used up.

Collision Theory and Reaction Rate Notes Rates of Chemical Reactions The amount of time it takes for a chemical reaction to come to completion is called the reaction rate Reaction rates are different for different reactions They can range from a fraction of a second to days or even years Why do different reactions have different rates? Reaction Mechanisms The overall progress of a chemical reaction can be represented at the molecular level by a series of simple elementary steps or elementary reactions. The sequence of elementary steps that leads to product formation is the reaction mechanism PowerPoint Presentation: The rate of reaction is proportional to the square of the concentration of A This means that if you doubled the concentration of A, the rate would go up 4 times (2 2). If you tripled the concentration of A, the rate would increase 9 times (3 2).What does rate of reaction mean? The speed of different chemical reactions varies hugely. Some reactions are very fast and others are very slow. What is the . Therefore, the reaction rate of a chemical reaction is stated as the change in concentration of a reactant or product per unit time, expressed as mol/(L∙s). Catalyst Definition: A substance which increases the rate of a chemical reaction by providing an alternative pathway with a lower. Define elementary reaction, reaction mechanism, and reaction intermediate. Determine the rate law from initial rates. Write the overall chemical equation from a.
