Type Of Reaction Flashcards
What is a combination reaction?
A combination reaction is a type of reaction where two or more substances combine to form a single compound.
What is a decomposition reaction?
A decomposition reaction involves breaking down a compound into two or more simpler substances, often using heat, light, or electricity.
What is a displacement reaction?
A displacement reaction occurs when a more reactive element displaces a less reactive one from its compound or
it involves the replacement of one element (or radical)by another element or (radical) in a compound
What is a double decomposition reaction?
It involves two ionic compounds exchanging ions to form new compounds, often leading to a precipitate, gas, or water formation.
What is a catalytic reaction?
A catalytic reaction involves a catalyst to increase or decrease the rate of a reaction without being consumed in the process.
What is homogeneous catalysis?
In homogeneous catalysis, the catalyst, reactants, and products are in the same phase (e.g., all gases or liquids).
What is heterogeneous catalysis?
In heterogeneous catalysis, the catalyst is in a different phase from the reactants and products (e.g., a solid catalyst with gaseous reactants).
What is a reversible reaction?
A reversible reaction is a chemical reaction where products can revert to reactants under suitable conditions.
What is thermal dissociation?
Thermal dissociation is the splitting of a compound into simpler substances due to heat, and it is reversible.
What is oxidation?
Oxidation is the addition of oxygen or the removal of hydrogen in a reaction.
What is reduction?
Reduction is the addition of hydrogen or the removal of oxygen in a reaction.
What is a redox reaction?
A redox reaction is a chemical reaction where oxidation and reduction occur simultaneously.

Double decomposition reaction.
What catalyst is used in the thermal decomposition of potassium trioxochlorate (V)?
Manganese (IV) oxide.
What catalyst is used in the Haber process for ammonia synthesis?
Iron.
What catalyst is used in the formation of margarine from vegetable oil?
Nickel.
What is the role of a catalyst in a chemical reaction?
A catalyst increases or decreases the rate of a reaction without being consumed or permanently changed.
What is the difference between homogeneous and heterogeneous catalysis?
In homogeneous catalysis, the catalyst and reactants are in the same phase, while in heterogeneous catalysis, they are in different phases.
Why are some reactions reversible?
Reactions are reversible when the products can react under certain conditions to reform the reactants.
What conditions favor the reversible decomposition of calcium trioxocarbonate (IV)?
Heating favors decomposition, while cooling or removing carbon (IV) oxide favors recombination.
Why is the thermal dissociation of ammonium chloride reversible?
Because the products (ammonia and hydrogen chloride) recombine to form ammonium chloride when cooled.
