Iron ore exists as Fe2O3. In order to remove the oxygen and generate pure iron, the oxygen must be transferred to another molecule. Carbon monoxide can be mixed with iron ore and carbon dioxide is generated. Carbon monoxide is produced in the combustion of carbon with limited oxygen. Calculate the value of ΔS° for the oxidation of carbon to carbon monoxide, 2C (s, graphite) + O2 (g) --> 2CO (g)

A. +179.4 J/mol K

B. +408.6 J/mol K

C. -408.6 J/mol K

D. +395.8 J/mol K
