Chemical dynamics

Chemical dynamics is a branch of chemistry and physics that studies the rates at which chemical reactions occur and the mechanisms by which they proceed. It is also known as reaction dynamics.

Overview

Chemical dynamics involves the study of chemical kinetics, which includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction's mechanism and transition states, as well as the construction of mathematical models that can describe the characteristics of a chemical reaction.

Reaction rates

The reaction rate of a chemical reaction is a measure of how the concentration of a reactant or product changes with time. It is usually expressed in terms of mol/L/s (molarity per second). The rate of a reaction can be influenced by a variety of factors, including the concentration of reactants, temperature, and the presence of a catalyst.

Reaction mechanisms

A reaction mechanism is a detailed sequence of individual steps that make up a chemical reaction. Each step has its own speed and contributes to the overall reaction rate. Understanding the mechanism of a reaction can help predict the outcome of the reaction under different conditions.

Transition states

A transition state is a high-energy state that reactants must pass through in order to become products. It is often represented as a peak in a potential energy diagram. The energy required to reach the transition state is known as the activation energy.

Mathematical models

Mathematical models in chemical dynamics are used to predict the outcome of a reaction under different conditions. These models often involve differential equations that describe the rate of change of the concentration of reactants and products.
