3B-3 & 3D Chemical Reactions and Equations

A process where substances (reactants) are transformed into new substances (products) through the breaking and forming of chemical bonds.

To add more reactant particles to a solution, which can speed up the reaction by increasing the likelihood of collisions between particles.

A type of chemical reaction that absorbs heat from its surroundings, resulting in a temperature decrease in the environment.

A type of chemical reaction that releases heat to its surroundings, resulting in a temperature increase in the environment.

The starting substances in a chemical reaction that undergo change to form products.

The substances that are formed as a result of a chemical reaction.

A number placed in front of a chemical formula to indicate how many molecules or moles of that substance are involved in the reaction.

A small number written after an element symbol that indicates the number of atoms of that element in a molecule.

The total area of the surface of a solid reactant that is exposed to a liquid or gas, which can affect the rate of reaction.

A substance that increases the rate of a chemical reaction without being consumed in the process.
