Using the constants from pg 1112, determine the change in entropy for the following reaction below and explain why is has the sign it does.
C6H12O6 + 6O2 --> 6H2O + 6CO2
Entropy changes in the surroundings will depend on how much heat is absorbed or given off by the system. Most systems and surroundings have give and take interactions of order and disorder.
