Chemical Reactions definitions Flashcards

The making or breaking of chemical bonds, transforming reactants into products, and resulting in changes in matter.

Forces that hold atoms together in molecules, formed by the sharing, transferring, or attraction of electrons, enabling chemical reactions and changes in matter.

Reactants are the starting materials in a chemical reaction, serving as the ingredients that undergo change to form products.

Reactions where energy is released, resulting in products with less free energy than the reactants.

Reactions that require an input of energy from the surroundings to proceed, resulting in products with higher energy than the reactants.

The energy available to do work in a system, determining the direction and spontaneity of chemical reactions.

The total energy of the products is less than that of the reactants, indicating energy release.

Occurs without the need for external energy input, driven by the system's inherent properties, often resulting in a net release of energy.

The energy required to initiate a chemical reaction, often provided by heat, light, or another form of energy.
