Defination / Uses

The environment of a chemical reaction is defined by standard temperature and pressure (STP), often known as standard conditions.
In chemistry, STP conditions are used to compare different sets of data.

The current STP, is defined by the IUPAC (International Union of Pure and Applied Chemistry), is 100 kPa (1 bar) absolute pressure and 273.15 K (0 °C) temperature. Because the volume of a gas changes with its temperature and pressure, it is important to specify the standard reference conditions of temperature and pressure when defining a gas volume or a volumetric flow rate in the commerce business. The standard conditions calculations are based on the ideal gas law. PV = nRT
