What is the standard enthalpy of a compound?
When a substance is formed from standard elements, heat is either released or absorbed. The heat associated with this is what we call the standard enthalpy of formation. This is an important characteristic because it tells us about the stability of the compound, as well as its reactivity with other compounds. Each element, in its standard form, is under the following conditions: at a pressure of 1 atmosphere and a temperature of 298.15 K. This table shows some standard enthalpies of a few different compounds.
