The Boudouard reaction is the equilibrium reaction between carbon dioxide gas and solid carbon to produce carbon monoxide gas. i.e. CO2+C⇌2 CO (endotherm). so option C is the right answer; adding some more info. By the Ellingham diagram, we know that the formation of CO2 is more stable than Co gaRead more
The Boudouard reaction is the equilibrium reaction between carbon dioxide gas and solid carbon to produce carbon monoxide gas. i.e. CO2+C⇌2 CO (endotherm). so option C is the right answer; adding some more info.
By the Ellingham diagram, we know that the formation of CO2 is more stable than Co gas at lower temperatures. Since the formation of CO is an endothermic reaction its more stable at higher temperatures when the free energy becomes more negative; the same can also be interpreted by the Ellingham diagram.
This reaction is more useful in the Blast furnace where CO acts as a reducing agent. Since the Boudouard reaction requires high temperature, it usually occurs near the tuyere zone ( where T ~ 2000 C). At the same time, we need to maintain the temperature there as CO formation is endothermic so it will reduce the temperature on formation.
Note: This reaction is a temperature-dependent equilibrium reaction.
