Question

The dissolving process is exothermic when?

the energy released in solvation is about the same as the energy used in breaking up solute-solute and solvent-solvent interactions.
the energy used in solvation exceeds the energy released in breaking up solute-solute and solvent-solvent interactions.
the energy released in solvation exceeds the energy used in breaking up solute-solute and solvent-solvent interactions.
the energy used in solvation is less than the energy released in breaking up solute-solute and solvent-solvent interactions.
the energy used in solvation is about the same as the energy released in breaking up solute-solute and solvent-solvent interactions.

Explanation / Answer

The exothermic process is when heat is released from a process.

Solvation involves : separation of particles of the solute (energy is needed) and then solvent molecules bond with solute particles (energy is released)

So if the energy released exceeds energy needed then the process is exothermic.

Answer: the energy released in solvation exceeds the energy used in breaking up solute-solute and solvent-solvent interactions.
