The partial derivative of this quantity over temperature with respect to temperature equals minus enthalpy divided by temperature squared.
The partial derivative of this quantity over temperature with respect to temperature equals minus enthalpy divided by temperature squared. For ideal mixing, the change in this quantity is equal to the total moles of substance times the gas constant times temperature times the sum over all components of the mole fraction times the natural log of the mole fraction. This quantity's natural variables are temperature and pressure. This quantity equals minus the (*) ideal gas constant times temperature times the natural log of the equilibrium constant. Equal to enthalpy minus the product of temperature and entropy, for 10 points, name this quantity which determines whether or not a reaction is spontaneous, named for an American chemist.
