spontaneous reaction

Question	Answer
Spontaneous reaction	Is a reaction that favors the formation of products at the conditions under which the reaction is occurring. A roaring bonfire (see next flashcard) is an example of a spontaneous reaction.
Image: Fogata (binary/octet-stream)	A fire is exothermic, which means a decrease in the energy of the system as energy is released to the surroundings as heat. The products of a fire are composed mostly of gases such as carbon dioxide and water vapor, so the entropy of the system increases during most combustion reactions.
This combination of a decrease in energy and an increase in entropy means that combustion reactions occur spontaneously.	Image: Combinacion Sht (binary/octet-stream)
