Thermodynamics govern reactions occur

  1. Jun 3, 2009 #1
    1. The problem statement, all variables and given/known data
    What concepts from Thermodynamics govern whether reactions occur or not?


    2. Relevant equations



    3. 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?

    like the K constant?

    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?
