Hey everyone welcome back. We need to label the following energy diagram for a reaction over time. And were given the labels below here. So for our first label we have the entropy of our reaction delta H of our reaction. Now we should recall that the entropy or delta H of our reaction is concerned with the energy that is released for our forward reaction. And so we would describe that energy here delta H. Of our reaction. Because this describes our reaction beginning with our reactant and proceeding all the way to our products here in the forward direction. Now we can move on to our second label which is our activation energy. So we should recall that our activation energy for our forward reaction is the energy that it takes to start up the reaction all the way to the highest point of energy for a reaction. So we would say that this here represents our activation energy and it goes all the way up to the peak of our reaction here. So our third label here now that we have activation energy and entropy of our reaction listed is products. So because this is a forward reaction, our products are going to be at the endpoint and we would say that this point here is our end point of our reaction. So we would list products here and then that leaves us with reactant as our last label which is the starting point of our reaction, which we would fill in here for our reactant. And so for our final answers, we have the following labels that we've filled in. So I hope that everything that I reviewed was clear. If you have any questions, please leave them down below, and I will see everyone in the next practice video.
