Lesson 10 - Equilibrium

Post by umbristo » Sun Jun 04, 2017 12:56 pm


I just wanted to clarify - are both graphs, depicted in the slide, examples of equilibrium? Or just the first one?

Hi umbristo,

Do you mean the graphs in slides 1 and 2, where the top one has to do with rates of the forward/reverse reactions and the bottom one has to do with the concentration of reactants/products? If so, yes, both have to do with equilibrium. More precisely, they have to do with how a reaction reaches equilibrium. The x-axis is time, and at first, the reaction is not at equilibrium -- but it reaches equilibrium by about halfway along the x-axis.

An important point here is that both graphs do indeed represent equilibrium. As a reaction reaches equilibrium, the rate of the forward & reverse reactions becomes the same, while the relative concentrations of products & reactants stabilize -- however, the absolute concentrations may be very different.

Hope this helps & good luck!
