    Laws of Thermodynamics First Law Total energy in the universe is constant Energy can neither be created nor  destroyed Energy can be transferred or transformed Second Law Every energy transfer or transformation  results in increased randomness in the  universe.

    Concept Enthalpy ( H): Total potential energy or heat  content Entropy ( S): Measure of randomness or  disorderliness Free energy ( G). The energy available to do  work under uniform temperature. G = H – T S where T = Absolute temperature in Kelvin (K= C + 273 )

  Chemical Reaction Examples of bond energy in kcal/mol C-C = 83, C-H = 99, C-O 84, C=0 = 174, O-H = 111, O=O = 118 Example of a chemical reaction CH 4 + 2 O 2 CO 2 + 2 H 2 O Bond energy (4 X 99) + (2 X 118) (2 X 174) + (4 X 111) H = H (reactants) 632 kcal/mol - H (products)792 kcal/mol
