We room asked to use bond energies come calculateΔHrxn because that the reaction: N2(g)+ 3 H2(g) → 2 NH3(g).

You are watching: Use average bond energies to calculate δhrxn for this reaction.

To calculation the ΔH°rxn usingbond energies, we’re going to use the following equation:

∆H°rxn=Hbond reactants-Hbond products

Let’s first figure the end what kind of bonds and how countless moles are current in every reactants and also products by drawing the Lewis structure since the provided bond energies are per mole.

Balanced Reaction: N2(g) + 3 H2(g)→ 3 H2(g) + 2 NH3(g)

*always make sure that the provided reaction is balanced

Therefore, we need to do the following first:

Step 1:Determine the central atom in this molecule.

Step 2:Calculate the total number of valence electrons present.

Step 3:Draw the Lewis framework for the molecule.

Reactants:
