Packet 11: Bonus 10
This quantity is defined as the maximum work extractable from a closed system in which temperature and pressure are held constant. For 10 points each:
[10m] Name this quantity whose change is less than zero for reactions that are thermodynamically favorable.
ANSWER: Gibbs free energy [or Gibbs energy; prompt on free energy]
[10h] The partial derivative of Gibbs free energy with respect to this quantity gives the chemical potential. The right side of the ideal gas law can be expressed as Boltzmann’s constant times this quantity times temperature.
ANSWER: particle number [accept answers indicating the number of particles or number of atoms or number of molecules; reject answers indicating “the number of moles of particles”]
[10e] J. Willard Gibbs also names a rule calculating the number of these things for a mixture. Namesake “transitions” between two of these things include melting and evaporation.
ANSWER: phases of matter [or states of matter; accept phase transitions]
