 Hi, this is Steven Esheba and I just want to help you out with the interpretation of a profile that one has obtained for finding the energy of activation. And I'm picking up on a previous video where we generated a profile, and I'm assuming that you've got that, and so you've loaded it back up. From this point it's pretty straightforward. What you'll want to do is go over here to this icon, and we want to go to Add, and the most convenient one I find is to go to this thing called Molecule List, and there you see it says Relative energies and kilojoules per mole, and so that loads that up, and so you can see it here. And then to make a graph of it, what we'll go here is now say plus, and hopefully that item shows up for you on the right, where you can do it that way, and now we have that graph on the right. I kind of like to use this icon to superimpose it on here, and now what we can do is we can essentially play, and you can see how the reaction is taking place, bond forming on the left and breaking on the right, and so on, and the other thing to take notice, in this case for the level of the B3 lip calculation that I did, the energy looks like from here, the starting place up to here looks like we have to go up to about 50 kilojoules per mole, so that would be the energy of activation for this reaction.
