[Q]: The USPS is often mistaken for a government-owned corporation (e.g., Amtrak) because it operates much like a business. It is, however, an ``establishment of the executive branch of the Government of the United States'', (39 U.S.C. § 201) as it is controlled by Presidential appointees and the Postmaster General. As a government agency, it has many special privileges, including sovereign immunity, eminent domain powers, powers to negotiate postal treaties with foreign nations, and an exclusive legal right to deliver first-class and third-class mail. Indeed, in 2004, the U.S. Supreme Court ruled in a unanimous decision that the USPS was not a government-owned corporation, and therefore could not be sued under the Sherman Antitrust Act.
[A]: is the us post office a federal agency?


[Q]: where (A) and (B) express the concentration of the species A and B (usually in moles per liter (molarity, M)). The exponents x and y are the partial orders of reaction for A and B and the overall reaction order is the sum of the exponents. These are often positive integers, but they may also be zero, fractional, or negative. The constant k is the reaction rate constant or rate coefficient of the reaction and has units of 1/time. Its value may depend on conditions such as temperature, ionic strength, surface area of an adsorbent, or light irradiation.
[A]:
can the order of a reaction be negative?
