The reaction between sodium chloride and water is slightly endothermic. Why does the reaction occur?
Because the process is
Chemical change is driven by
The entropy change,
When we write the
For your chemical reaction that represents the dissolution of salt, we write,
The process, is indeed slightly endothermic, in that we have to input energy to break the strong electrostatic bonds that persist between positive and negative ions throughout the entire ionic lattice. Neverthless, because
