Second Figure

Certainly! The Second Figure illustrates the process of how a chemical reaction occurs, focusing on the energy involved. It shows the starting substances (reactants), the energy needed to initiate the reaction (activation energy), and the resulting substances (products). The graph typically displays energy on the vertical axis and progress on the horizontal. The curve rises as energy is absorbed to break bonds, peaks at the activation energy barrier, then falls as new bonds form, releasing energy. This helps visualize why some reactions need a spark or heat to start and how energy changes during the process.
