Front

Substance that increases the rate of a chemical reaction without being changed or used up.

Back

catalyst

Front

Chemical reaction requiring constant energy input, absorbing more energy to break bonds than released in new bonds.

Back

Endothermic reaction

Front

Chemical reaction where multiple reactants form one product.

Back

Synthesis reaction

Front

Chemical reaction where one reactant breaks down into multiple products.

Back

Decomposition reaction

Front

Speed of a chemical reaction.

Back

Reaction rate

Front

Energy needed to start a chemical reaction.

Back

Activation energy

Front

Biochemical catalyst that speeds up reactions in living things.

Back

Enzyme

Front

Chemical reaction releasing energy; less energy to break reactant bonds than released in product bonds.

Back

exothermic reaction

Front

Chemical reaction where ions switch places in one (single) or two (double) compounds.

Back

replacement reaction

Front

Chemical reaction where a substance reacts rapidly with oxygen, producing CO2, water, and energy; known as burning.

Back

combustion reaction
