What type of chemical reaction is without outside energy? Spontaneous (exergonic/downhill) 
NOT INSTANTANEOUS 
-decreasing enthalpy and increasing entropy 
 
What is the equation for Free Energy? deltaG=deltaH-TdeltaS 
-free enrgy=enthalpy-(temp.)(entropy;disorder) 
-high deltaS=low delta G 
 
Entropy Disorder: 
-breakdown: increase in disorder, more parts 
-synthesis: decrease in disorder, less parts
