Enthalpy-Entropy & chemistry

[405509920]

In the LS series we learned about the dynamic between states of enthalpy and entropy. In essence, entropy was the disorder of a system and it took energy(enthalpy) to keep a system together. Its the explanation as to why things degrade. On a chemical level, how does the natural process of degradation happen?

I'm not sure if generally degradation applies to chemistry, but I know that systems will tend toward higher entropy (more randomness), such as gases spreading out in a container, etc. This is applied when determining the gibbs free energy of the reaction (whether it is thermodynamically favorable or not). I think we'll learn a bit more about it in 14B, where a reaction that increases entropy would tend to be more favorable.
