[Q]: This quantity can be defined as minus the temperature times the derivative of entropy with respect to particle number. The Gibbs factor is a generalization of the Boltzmann factor that takes this quantity into account. Usually defined as the derivative of the Helmholtz free energy with respect to particle number, FTP name this quantity which governs particle flow, as particles flow from systems with higher values to systems with lower values.
[A]: Science

[Q]: This ruler established a code which mandated that pavilions be owned by only one family and ordered the execution of the Duke of Biron partially for conspiring with Savoy, which was forced to surrender Bresse to him by the Treaty of Lyons.

[A]: History

[Q]: The Krutzsch process produced about a ten percent aqueous solution of this compound, but was never commercialized. This compound is produced commercially by sending bubbles of air through a solution of anthracene, leading to the autoxidation of 2-alkyl anthrahydroquinone to a 2-alkyl anthraquinone. That process is known as the AO process and was invented by Riedl and Pfleiderer. This compound is found with ferrous salts in Fenton's reagent, and oxidizes sodium hypochlorite to give oxygen. A three percent aqueous solution of it is useful for treating minor wounds. It is broken down to oxygen and water by catalase. For 10 points, name this oxidizing agent with formula H2O2.
