A global representation of this quantity is calculated by considering the coupling constant to be a continuous variable in lambda-dynamics. Beta times the change in this quantity is taken to be the argument of the Metropolis function when calculating changes in this quantity with the Bennett acceptance ratio. The value of this quantity along a given coordinate (10[1])is called the potential (-5[1])of mean force. Thermodynamic integration is used to calculate changes in this quantity in molecular dynamics. Isolated systems at constant temperature minimize this quantity at thermal equilibrium. A form of this quantity equals negative Boltzmann’s constant times temperature times the natural log of the canonical partition function. For 10 points, enthalpy minus the product of temperature and (-5[1])entropy gives a form of what quantity named for J. W. Gibbs? ■END■ (10[2])
