  • $\begingroup$ So some molecules provide sufficient energy to make the product revert to reactant state, what is the origin of this energy and why and how is this energy causing this revert? $\endgroup$

  • $\begingroup$ I understand your point, but I'm still confused as to how this 'energy' can cause such. could you please explain it in molecular level in detail? $\endgroup$

  • $\begingroup$ @Yoojin, read 1. and 2. View the references. If you don't understand those links, ask a specific question. $\endgroup$

  • $\begingroup$ I see. I have a question regarding the video by Jim Schneider, when the tube was placed from the hot water container to the cold water container, more N204 formed in a short time span as the visible changes could be observed as the color of tube lightened. I can only conclude that cold temperature favors the formation of N2O4 as equilibrium shifts towards right. But in order to go from brown to colorless, bonds need to be formed as N2O4 is the product. But in cold temperature, collision's frequency decreases thus reaction rate decreases. So how does the color change occurred? $\endgroup$

  • $\begingroup$ "Decrease"does not mean "cease". $\endgroup$
