Homework Statement
Quartz, SiO2(s), does not spontaneously decompose to silicon and oxygen at 25C in the reaction:
SiO2(s) -> Si(s) + O2(g)
even though the standard entropy change of the reaction is large and positive (delta S = +182.02 J K-1). Explain.
-------------------------
So, how do I explain that this is the case? The book only describes that when delta S > 0 the reaction is spontaneous with no exceptions.
Thanks!
