Heterogeneous reaction

Heterogeneous reaction, any of a class of chemical reactions in which the reactants are components of two or more phases (solid and gas, solid and liquid, two immiscible liquids) or in which one or more reactants undergo chemical change at an interface, e.g., on the surface of a solid catalyst.

What is an example of a heterogeneous reaction?

Some examples of heterogeneous reactions are the reaction of solid metals with acids, the corrosion of iron, the electrochemical reaction occurring in batteries and electrolytic cells are all subjected to a heterogeneous reaction.

What is heterogeneous and homogeneous reaction?

Homogeneous and heterogeneous reactions

Homogeneous reactions are chemical reactions in which the reactants and products are in the same phase, while heterogeneous reactions have reactants in two or more phases. ... A reaction between a gas and a liquid, a gas and a solid or a liquid and a solid is heterogeneous.

How do you know if a reaction is heterogeneous?

A heterogeneous reaction is a chemical reaction where the reactants are in different phases from each other. In a homogeneous reaction, the reactants are in the same phase as one another.

What are different types of heterogeneous reactions?

• ➢ Dissolution of solids (e.g. MgCO3(s) + HNO3(l))
• ➢ Chemical Vapor Deposition (SiH4(g) → Si(s) + 2H2)
• ➢ Sublimation (U(s) + 3 F2(g) → UF6(g))
• ➢ Reduction of solid oxides (NiO(s) + H2(g) → Ni(s) + H2O(g))
• ➢ Metals oxidation (Zn(s) + O2(g) → ZnO(s))
• ➢ Catalytic reactions.
