To calculate the ΔH°rxn using bond energies, we’re going to use the following equation:
Let’s first figure out what kind of bonds and how many moles are present in each reactants and products because the given bond energies are per mole.
Balanced Reaction: CH4(g) + H2O(g) → CO(g) + 3H 2(g)
*always make sure that the given reaction is balanced
Draw the structure of each compound.
The major industrial source of hydrogen gas is by the following reaction:
CH4(g) + H2O(g) → CO(g) + 3H 2(g)
Use bond energies to predict ΔE for this reaction.
