Types of Reactions

Front

What is an exothermic reaction?

Back

A reaction that releases energy, usually in the form of heat or light.

Front

What is an endothermic reaction?

Back

A reaction that absorbs energy from its surroundings.

Front

What type of reaction is characterized by the formation of new substances?

Back

Chemical reaction.

Front

What is a synthesis reaction?

Back

A type of reaction where two or more reactants combine to form a single product.

Front

What is a decomposition reaction?

Back

A reaction where a single compound breaks down into two or more simpler products.

Front

What is a single displacement reaction?

Back

A reaction where one element replaces another in a compound.

Front

What is a double displacement reaction?

Back

A reaction where two compounds exchange ions or bonds to form new compounds.

Front

What is the role of energy in chemical reactions?

Back

Energy is either absorbed or released during chemical reactions, influencing the reaction's temperature and spontaneity.

Front

How does temperature affect reaction rates?

Back

Increasing temperature generally increases reaction rates by providing more energy to the reactants.

Front

What is the significance of catalysts in chemical reactions?

Back

Catalysts speed up reactions without being consumed, lowering the activation energy required.
