Thermodynamics processes and

A substance will dissolve, quite simply, if it is energetically favourable for it to do so. If the sum of the energies required to break apart those forces holding the potential solute together and to separate the solvent molecules from one another is outweighed by the energy released on solvation, then the substance will dissolve. However, dissolution is a kinetic as well as a thermodynamic process, and solutes that dissolve slowly may be accelerated greatly by the employment of heat or ultrasound.

The second law deals with the spontaneous evolution of a thermodynamic process and the efficiency of conversion between different forms of energy, particularly between work and heat. It is intimately linked with the notion of entropy. The work can be transformed spontaneously and integrally in heat, such that fV = JQ. On the contrary, the conversion of heat in work is never spontaneous. 

A thermodynamic process is anything that changes the thermodynamic variables in the system or environment. A thermodynamic process can be effected in various ways. Note the difference between a thermodynamic process and the way to effect the process in practice, i.e., the realization of the thermodynamic process.

Corrosion is a thermodynamic process and therefore favored by nature. One can never say that there is no corrosion happening unless it means either or both of the following ...
