is the combustion of propane exothermic
Is this reaction Endothermic The combustion of propane in oxygen to produce carbon dioxide and water vapor.   All the combustion reactions I know of are exothermic because heat is released instead of absorbed. And propane gives more energy than methane cause it has more Cs and H â¦ s to react with Oxygen, so one mole of propane will react more and form more product than one mole of methane and giving out more energy.
