Answer 1

Answer:

Solids do not react with solids at room temperature even of thermodynamics is favorable. High temperature must be used. Solid-solid reactions are simple to perform, starting materials are often readily available at low cost and reactions are “clean” i.e. do not involve other chemical elements.

Answer 2

The reaction is called homogeneous reaction.

• Homogeneous reactions are the reactions where substrate and products both are in same phase.
• Heterogeneous reactions are the reactions where two or more phases are involved in the form of substrate and products.
• Reaction between two solids is possible due to melting of both the substrates, which subsequently react. (Occurs for some substances)
