Chem 202 Dr. Kuta Test 2 Chapters 44 and 45 Chapter 44 44.1 - Entropy, Qualitatively There is a simple equation for entropy S = k lnW S = entropy k = Boltzmann constant (1.381 x 10 -23J/K) without thermal energy then W can exist as 1 There is a connection between energy and temperature within this equation Entropy - is a measure of the options for the motional energy of a system at some specified temperature Exothermic - J’s leave the system Endothermic - J’s enter the system 44.2 - Entropy Quantitatively Only final and initial states count These are the equations you will need to answer any problems, it is very simplistic. o H = H final Hiniti
