Chemical Reactions and Equations

These flashcards cover key vocabulary terms and concepts related to chemical reactions and equations.

Chemical Reaction

A process in which reactants undergo a transformation to form products.

Chemical Equation

A symbolic representation of a chemical reaction using symbols and chemical formulae.

Reactants

Substances that undergo a chemical change in a reaction.

Products

Substances formed as a result of a chemical reaction.

Collision Theory

The theory stating that for a reaction to occur, reactant particles must collide with sufficient energy.

Rate of Reaction

The speed at which reactants are converted into products in a chemical reaction.

Concentration

The amount of a substance in a given volume; often refers to the number of moles.

State Symbols

Symbols indicating the physical state of a substance in a chemical equation (s, l, g, aq).

Balanced Equation

A chemical equation with equal numbers of each type of atom on both the reactant and the product sides.

Factors Affecting Reaction Rate

Factors such as temperature, particle size, and concentration that influence how quickly a reaction occurs.
