Okay, using the thermodynamic information, calculate the standard reaction free energy following the chemical reactions.
00:09
So in this case, you have the methane, react with two more oxygen, produce one more carbon dioxide, and two more water.
00:29
So if we want to calculate the delta g of this reaction.
00:34
So simply, what we need to do, if you have the data, we simply know, right, equals to two times the formation energy.
00:51
The gives free energy of the formation energy of the water gap vapor, plus two times the gives free energy, formation energy, of the co2, minus two times the gives free energy of the oxygen, and minus two times gives free formation energy of the methane.
01:22
So if you have the table, simply just plug in all the numbers, right, you can get the answer.
01:27
So please be realized the free energy of the auction is actually zero since it's a pure compound, right? sometimes it would be hard.
01:39
You only have the delta h and delta s.
01:43
So the first thing is you calculate the delta h first, right? equals to 2 times enthalpy of the formation of the water vapor, plus there's no two here, right? formation enthalpy of the carbon dioxide, minus, there's no two here either...
