Taking the derivative of this quantity with respect to particle number yields chemical potential. It can be found by multiplying the natural log of the equilibrium constant by negative one, the ideal gas law, and temperature, while it can also be found through subtracting the product of temperature and entropy from (*) enthalpy. When this quantity is negative for a given reaction, that reaction is spontaneous. For 10 points, name this thermodynamic quantity, which is the amount of usable energy in a system and which is symbolized capital G.
