The standard molar enthalpy of formation of NH3(g) is –45.9kJ/mol. What is the enthalpy change if 9.51 g N2(g) and 1.96 gH2(g) react to produce NH3(g)? NOTE: The question is asking- Howmuch heat is released when the reaction is performed under thestated conditions. To answer the question, you must first determinewhich reactant is the limiting reactant. A) –10.3 kJ B) –20.7 kJ C)–29.8 kJ D) –43.7 kJ E) –65.6 kJ
