Research is being carried out on cellulose as a source of chemicals for the production of fibers, coatings, and plastics. Cellulose consists of long chains of glucose molecules (C6H12O6), so for the purposes of modeling the reaction we can consider the conversion of glucose to formaldehyde (H2CO). Calculate the heat of reaction for the conversion of 1 mole of glucose into formaldehyde, given the following thermochemical data: H2CO (g) + O2 (g) → CO2 (g) +H2O (g) ΔH°comb = –572.9 kJ/mol 6C (s) + 6H2 (g) + 3O2 (g) → C6H12O6 (s) ΔH°f = –1274.4 kJ/mol C (s) + O2 (g) → CO2 (g) ΔH°f = –393.5 kJ/mol H2 (g) + 1/2 O2 (g) → H2O (g) ΔH°f = –285.8 kJ/mol What is the ΔH°rxn for the reaction below? C6H12O6 (s) → 6H2CO (g)

Question
Research is being carried out on cellulose as a source of chemicals for the production of fibers, coatings, and plastics. Cellulose consists of long chains of glucose molecules (C6H12O6), so for the purposes of modeling the reaction we can consider the conversion of glucose to formaldehyde (H2CO).
Calculate the heat of reaction for the conversion of 1 mole of glucose into formaldehyde, given the following thermochemical data:
H2CO (g) + O2 (g) → CO2 (g) +H2O (g) ΔH°comb = –572.9 kJ/mol
6C (s) + 6H2 (g) + 3O2 (g) → C6H12O6 (s) ΔH°f = –1274.4 kJ/mol
C (s) + O2 (g) → CO2 (g) ΔH°f = –393.5 kJ/mol
H2 (g) + 1/2 O2 (g) → H2O (g) ΔH°f = –285.8 kJ/mol
What is the ΔH°rxn for the reaction below?
C6H12O6 (s) → 6H2CO (g)
