[Thermodynamics: For each of the five options, discuss in detail why it is correct or wrong. Identify also the chemistry concept that will be used to answer the question.] In normal chemical storage, the element sulfur remains unreacted with oxygen in the atmosphere. However, it is impossible for sulfur and oxygen to react spontaneously to form gaseous sulfur dioxide. This is most likely to happen:
