Question

c(s) + air at 1273k gives ​

Answer 1

Answer:

CO2 + H2O

Explanation:

Combustion Reaction of carbon

Answer 2

Answer:

When carbon reacts with air, it gives out either CO₂ or CO.

Explanation:

• When carbon is made to react with excess supply of oxygen, it produces CO₂ (carbon dioxide) and gives out heat as new bonds are formed.
• C (s) + air → CO₂ (g) + Δ
• This type of reaction is called a complete combustion reaction and it is highly exothermic.
• When carbon is made to react with a limited supply of oxygen, it produces CO (carbon monoxide) and gives out heat as new bonds are formed.
• C(s) + air (limited) → CO (g) + Δ
• This reaction is called a incomplete combustion reaction and it is exothermic as well.

Conclusion:

We can either get CO₂ or CO depending upon the amount of air supplied.
