Question

Use the molar bond enthalpy data in the table to estimate the value of ∆H in for the equation NH3(g) + 2O2(g) → HNO2(g) + H2O(g).

A. 116 kJ/mol
B. 228 kJ/mol
C. 236 kJ/mol
D. 454 kJ/mol

Answer 1

Without the correct molar bond enthalpy data related to the NH3 and O2 reaction provided, it is not possible to estimate the enthalpy change for the reaction NH3(g) + 2O2(g) → HNO2(g) + H2O(g).

Step-by-step explanation:

To estimate the enthalpy change (ΔH) for the reaction NH3(g) + 2O2(g) → HNO2(g) + H2O(g), we need to consider the energy required to break the bonds in the reactants and the energy released when new bonds form in the products. Unfortunately, the provided information is not directly related to the reaction in question, as it contains data for different reactions or substances. Therefore, without the appropriate bond enthalpies for the chemical species involved in the given reaction of NH3 and O2, we are unable to calculate the enthalpy change accurately based on the given data.
