Which step involves breaking intermolecular bonds among solvent molecules during the solution formation process?

The step that involves breaking intermolecular bonds among solvent molecules during the solution formation process is indeed the second step. In the context of solution formation, specifically when a solute is dissolved in a solvent, the process can be broken down into three key steps.

In the first step, solute particles are separated from each other, which involves overcoming the forces that hold the solute together. This step requires energy and is essential for allowing solute particles to disperse in the solvent.

The second step, which is the correct answer, requires breaking the intermolecular forces among solvent molecules. This step is crucial because, for the solute to be integrated into the solvent, the solvent must make space for the solute particles. Breaking these intermolecular bonds between solvent molecules involves energy input, and it allows the solute to interact with the solvent effectively.

In the third step, new interactions are formed between the solute and solvent molecules. This step often results in a release of energy, as new bonds are formed which stabilizes the solution.

Thus, the second step is specifically focused on disrupting the interactions among solvent molecules to facilitate the solute's introduction into the solvent, making it critical in the overall process of solution formation.
