The value of ΔS° for the oxidation of carbon to carbon monoxide,
2C (s,graphite) + O₂ (g) → 2CO (g)
Is ________ J/K ∙ mol.Carbon monoxide is produced in the combustion of carbon with limited oxygen.

Question

Quizplus · Accepted Answer

The reaction involves the conversion of solid carbon and gaseous oxygen to gaseous carbon monoxide. The increase in the number of gas molecules from 1 to 2 results in an increase in entropy, hence ΔS° is positive.
