Күн бұрын

This chemistry video tutorial focuses on potential energy diagrams for endothermic and exothermic reactions. It also shows the effect of a catalyst on the forward and reverse activation energy. It describes the relationship of the enthalpy of a reaction with the potential energy difference of the reactants and products. It also shows you how to identify the transition state or activated complex as well as any intermediates. This video shows you how to draw a 2 step PE diagram and a 3 step potential energy diagram. In addition, it shows you how to identify the slow step or the rate determining step.

This guy is the sole reason I’m doing good. My teachers are very very intelligent but he makes things very simple, takes his time. My teacher has notes pre-made and still takes 80 mins to explain what he does perfectly in 8-15 mins. Truly a legend

Thanks, my chem teacher (normal chem) isn't teaching us anything because she dumbs down the class for the people who don't care about their grades. This is actually pretty helpful. I learned more in this video than we did in a 45 minute class period where she was saying the same stuff over and over. The way you explain these topics is simple and time-efficient. My teacher didn't even tell us what enthalpy was, merely that we should see it and think "change in heat" (because delta-H). Thanks for the help.

Can you answer this question? Do these diagrams show Internal energy or just the chemical potential energy? From thermodynamics I know that it's the change in Internal energy (without pressure or volume change) that equals heat exchange.
