In chemistry and thermodynamics, the standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements in their reference state, with all substances in their standard states. The standard pressure value p = 10 Pa (= 100 kPa = 1 bar) is recommended by IUPAC, although prior to 1982 the value 1.00 atm (101.325 kPa) was used. There is no standard temperature. Its symbol i… WebExplanation: X → Y and Y → Z In the process of Y → Z, heat flows into the system so q > 0. In the process of X → Y, the gas is expanding, it is doing work on the system so q > 0. In the process Z → X, heat is flowing out of the system so q < 0. A) A function that depends on what route is taken between start and finish.
