Covalent bonds standard enthalpy change

The standard enthalpy change for the conversion of a gaseous covalent molecule into gaseous atoms is the sum of the bond enthalpy terms for the bonds in that molecule. Bond enthalpy terms do not vary greatly from one molecule to another. ... [Pg.39]

The energy in question is called the standard bond enthalpy. It can be tested, and the values exist in standardized tables that can be referenced in textbooks. They can be used to determine the stability of compounds that can be either covalent or ionic. However the calculation Isreaks down at times, for example if values are very low positive or negative values, the results can t always be trusted. To compensate for this, a chemist can change the conditions under which the reaction takes place to better suit crystal formation. [Pg.295]
