Final answer:
The movement of electrons in a reaction is depicted through mechanisms such as the electron transport chain and reaction steps. For example, the decomposition of ozone involves a two-step mechanism where ozone molecules break down into oxygen molecules and atoms, and then recombine to form more oxygen molecules.
Step-by-step explanation:
The mechanism that properly shows the movement of electrons in a reaction is crucial for understanding how a chemical reaction proceeds. When we discuss the electron transport chain, as in the context provided, we are referring to a series of compounds that transfer electrons from electron donors to electron acceptors via redox reactions, and the transfer of these electrons releases energy which is used to form ATP.
In the case of the decomposition of ozone, the reaction mechanism evidently consists of two steps. The first step involves the splitting of an ozone (O₃) molecule into an oxygen molecule (O₂) and a single oxygen atom, which then reacts with another ozone molecule to form two molecules of oxygen. This step-by-step description allows us to understand how reactions proceed, by tracking the path of electrons throughout the process.
