You are analyzing the combustion of ethane: 2C2H6(g)+7O2(g)→4CO2(g)+6H2O(l)2\text{C}_2\text{H}_6(g) + 7\text{O}_2(g) \rightarrow 4\text{CO}_2(g) + 6\text{H}_2\text{O}(l). After calculating ΔH°rxn\Delta H°_{rxn} using the table data, you want to verify your result using bond energies. However, you realize that the ΔH°f\Delta H°_f method and bond energy method may give slightly different results. What is the most likely reason for any discrepancy? Figure accompanying this question
