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) + 1/2O₂ (g) → H₂O (g)     ΔH°_f = -285.8 kJ/mol 

C₆H₁₂O₆ (s) → 6H₂CO (g)     ΔH°_rxn = ?
