Gas -solid reaction is an example of​

Answer 1

Answer:

Making dry ice or solid carbon dioxide involves the removal of gaseous carbon dioxide

Answer 2

Condensation or Vaporization of gas to form solid is a example of gas - solid reaction.

Explanation:

• Gas - solid reaction focuses on four phenomena such as external mass transfer, pore diffusion, adsorption and chemical reaction.
• The gas - solid reaction system is the interaction of a single particle with a moving gas stream.
• Direct reduction of iron ore to iron by a mixture of carbon monoxide and hydrogen is also an example of solid - gas reaction.
• The reaction is carried out in direct reduction.
• Gas - solid reaction also occurs in extractive metallurgy.
• The process takes place is called roasting.
• Roasting consists of thermal gas - solid reactions, includes oxidation, reduction, chlorination, sulfating reactions.
