A combustion reaction is describes as a carbon source reacting with oxygen and producing carbon dioxide and water. A common example of this reaction is methane reacting with oxygen gas in the following reaction:
CH4(g) + 2O2 (g) yields CO2 (g) + 2H2O (g)
What would the standard entropy change be, if 20 g of methane reacted with 20 g of oxygen?
Answer: -1.626 J K-1
