The standard reaction enthalpy for following reaction has to be calculated. N H 4 N O 3 ( s ) → N 2 O ( g ) + 2 H 2 O ( g ) Concept Introduction: Enthalpy is the amount energy absorbed or released in a process. The value of standard enthalpy change ΔH ο of the given reaction is calculated by the formula, ΔH ο = ∑ n p ΔH f ο ( products ) − ∑ n r ΔH f ο ( reactants )

Expert Solution
Answer to Problem 101QRT
The standard reaction enthalpy of given reaction is -36.03 kJ.
Explanation of Solution
Given: NH4NO3(s)→N2O(g)+2H2O(g)
Using the above given reaction enthalpy is calculated by subtracting the summation of formation of products from the summation of formation enthalpy of reactants.
