Eg. For most equilibrium reactions the reactant and product are at approximately the same energy, which is why they are interconvertible. | |

A reaction is 0% complete if the medium contains only reactants and 100% complete if it only contains products. We could instead plot the energy or some other variable as a function of time, but then we would be involving the rate of the rxn, etc so instead we make up a variable called reaction progress that represents how much of the reaction has been completed. | |

| Dec 17, 2019 at 16:35 | comment | added | Vishal Jain | I haven't done so before. I am trying to follow this lecture course for context in my current lecture course on thermodynamics. This is the first time the professor in this online lecture series has drawn such a graph, I am guessing this is a physical chemistry thing. If you understand the graph, could you please post an answer explaining it? | |
