What concepts from Thermodynamics govern whether reactions occur or not?

Homework Equations

The Attempt at a Solution

Activation energy-need some source of energy to start it-like pressure or light.
Entropy-but why?

Anything else, I'm sure there is more, but I don't understand it very well.

Have you studied about how free energy relates the equilibrium constants of reactions?

 

[aimslin22]

like the K constant?

 

[Ygggdrasil]

Yes. How is the change in free energy during a reaction (ΔG) related to the equilibrium constant (K)? What does the equilibrium constant tell you about the reaction?
