the main theme of this particular segment of our chemistry class is systems outside equilibrium and we have done some of the mathematics and so on with an initial discussion about delta g and we use the equation equals the delta g naught plus rtl and q right our t l and q and we also went into electrochemistry and we use the nern's equation and the reason why we have some of these and the reason why the delta g or the e that we measured is non-zero value or even positive or negative is because the system is outside equilibrium because if the system is at equilibrium these are going to be zero at equilibrium right and we measure a non-zero number because they're not so we're going to take one more step further with the systems output outside equilibrium with the rates of reactions and that not only that we're interested in how much energy that we can extract out of the particular chemical reaction we also want to know how fast the reaction happens right so that's essentially kind of the major topic um what where that we went into so of course now we're going to start to explore the rates of reaction
