RMX Posted January 17, 2012 Share Posted January 17, 2012 Would anyone happen to know the heat of formation for lithium. Also it would help if someone knew a way of determining the heat of formation of the reactants of a reaction when you only know the products.

mississippichem Posted January 17, 2012 Share Posted January 17, 2012 (edited) By definition, the heat of formation of an element in its standard state is zero. The definition of the standard enthalpy of reaction is: [math] \sum H^{o}_{rxn}=\sum H^{o}_{prod}-\sum H^{o}_{react} [/math] Edited January 17, 2012 by mississippichem 1 Link to comment Share on other sites More sharing options...
