2H2O ==> 2H2 + O2
This a typical decomposition reaction; a single material forming more than one on the other side.
I'm not sure what you want with "driving force" but I would answer that both H2 an O2 are gases so delta S increases(that's good). However, H2O won't do this on its own; energy must be added to make it decompose. You may be talking about the latter and not the former.
Hi DrBob222 i mean the evidence of the reaction pls
Have you done this? or can you envision it? Liquid disappears; gases appear.
