# Problem: 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 = ?

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) → CO(g) + H2O (g)     ΔH°comb = -572.9 kJ/mol

6C (s) + 6H2 (g) + 3O2 (g) → C6H12O(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 = ?
