Question
The dissolving process is exothermic when :
Options
A.The energy released in solvation exceeds the energy used in breaking up solute-solute and solvent-solvent interactions.
B.The energy used in solvation exceeds the energy released in breaking up solute-solute and solvent-solvent interactions.
C.The energy released in solvation is about the same as the energy used in breaking up solute-solute and solvent-solvent interactions.
D.The energy used in solvation is about the same as the energy used in breaking up solute-solute and solvent-solvent interactions.
Solution
solvent-solvent interaction and solute-solute interaction are endothermic while solvent-solute interaction is exothermic. The sum of the three interaction determines whether ᐃHsol is endothermic as exothermic.
