CHEMISTRY GLOSSARY

Spontaneous process is a process that occurs without outside intervention. No external forces are required to keep the process going, although external forces may be required to get the process started. For example, the burning of wood is spontaneous once the fire is started. The combination of water and carbon dioxide to reform the wood and oxygen is NOT spontaneous! Spontaneity is independent of rate. To be spontaneous a process must increase the entropy of the universe.
