Question

What do you observe when:

Carbon dioxide is heated with coke?

Answer 1

• Coke and charcoal are good reducing agents.
• Due to their strong affinity for oxygen. Due to their strong affinity for oxygen, they can remove oxygen from various oxides.
• At high temperatures, coke and charcoal reduce:
• Carbon dioxide to give carbon monoxide.
• ${\mathrm{CO}}_2^{}\left(\mathrm{g}\right)+\mathrm{C}\left(\mathrm{s}\right)\underset{}{\to 2\mathrm{CO}\left(\mathrm{s}\right)}$.
• Carbon is used to reduce non-metallic oxide to the metal. (Reduction).

When carbon is used as a reducing agent it is called coke.

conclusion: Carbon dioxide is heated with coke and reduced to carbon monoxide.
