1.	The molar heat of formation of NH_(4)NO_(3)(g) is -367.54kJ and thoseof N_(2)O(g) and H_(2)O(l) are +81.46kJ and -285.78 kJ respectively at 25^(@)C and 1.0 atmosphericpressure. Calculate Delta H and DeltaU for the reaction.
Answer» Solution :`NH_(4)NO_(3)(s) rarrN_(2)O(g) + 2H_(2)O(l), DELTAH _("reaction") = SigmaDelta_(f) H (` Products `) -SigmaDelta_(f) H (` Reactants) `Deltan_(g) =n_(p)- n_(r) = 1-0 = 1` `DeltaU = DeltaH - Delta n_(g) RT`
