Syphon and the Potential Energy Diagrams Thew is a very helpiul qualrlaliw analog). hetwern syphon and the potenrial energ\ diagram ss shown below. The fltlid will nut stan tlowing traction will not start, tmm the higher \essrl f h m the reactamst to rhe lnwcr w s r d (to the products) unless enough energy -~ has been provided so that it can surmount the barrier h r ( E r ) from which spontsnews~flowoccurs. The analogy as well demonstrates that the greater the difference between the heights hf the two vessels (between the energy levels of the readants and the products) the faster the flow (the reaction), and the smaller this difference the closer to the reversibility it would be.
