Chapter 6
Catalyst Ð A substance that
changes the rate of reaction with out being consumed or changed significantly.
Combustion Reaction Ð The
oxidation reaction of an organic compound, in which heat is released.
Chemical energy Ð the energy
released when a chemical compound reacts to form new compounds
Chemical reaction Ð a
representation of a chemical reaction that used symbols to show the
relationship between the reactants and products.
Chemical equilibrium, - A
state of balance in which the rate of a forward reaction equals the rate of the
reverse reaction and the concentration of reactants and products remains
unchanged.
Decomposition reactions - A
reaction in which a single compound breaks down to form two or more simpler
substances.
Double Displacement Reaction
Ð A reaction in which a gas, solid precipitate, or a molecular compound forms
from the apparent exchange of atoms or ions between two compounds.
Electrolysis- The process in
which an electric current is used to produce a chemical reaction, such as the
decomposition of water.
Endothermic reactions - A chemical reaction requiring heat
Enzyme Ð a type of protein
that speeds up metabolic reactions in plants and animals without being
permanently changed or destroyed
Exothermic reactions Ð a
chemical reaction in which heat is released to the surroundings
Mole Ratio Ð The relative
number of moles of the substances required to produce a given amount of product
in a chemical reaction.
Oxidation Reduction Reaction
Ð any chemical change in which one species is oxidized (loses electrons) and
another species is reduced (gains electrons). It is also called a redox reaction.
Product Ð A substance that
forms in a chemical reaction
Radical Ð An organic group
that has one or more electrons available for bonding.
Reactant Ð a substance or
molecules that participates in a chemical reaction.
Single Displacement Reaction Ð A reaction in which one element or radical takes the lace of another element or radical in a compound.
Substrate - A part, substance or element that lies beneath and supports another part, substrate, or element; the reactant in reactions catalyzed by enzymes
Synthesis Reaction Ð a reaction in which two or more substances combine to form a new compound.
