   how do you determine this, do you hve to take exothermic or endothermic reactions into acount or what

   Spontaneous processes result in the lowering of the total Gibbs Free Energy (G).
   
   For a chemical reaction to be spontaneous, ΔG must be negative.
   It is possible to have both exothermic (ΔH < 0) as well as endothermic (ΔH > 0) spontaneous reactions.
   
   ΔG = ΔH – T * ΔS
   Where ΔG is the change in the Gibbs Free Energy, ΔH is the change in enthalpy, ΔS is the change in entropy, and T is the temperature the reaction occurs at (in Kelvin).
