and lastly, this solar question that is a graph off energy versus reactions progress. So we have a graph and they're asking us, very reactant. Where the products Where is the activation energy? What is the LP and where is the activated complex? So we start the reaction here, right? So this is going to be our reactant and reaction ends here. So we will. How are products over here now? The activated complex means Remember, we're talking about all these molecules going up on this energy. Hell, this thing. And at here, there's some frequency off molecules which could go through this deal, and we call this activated complex. And what is this health? This hill is what we call the energy off activation. So to be able to become activated complex, the molecules first needs Thio. Walk up this hill and this hill is the activation energy. That is why, if your activation energy is high, are your reactive molecules needs to walk up a higher hill and the reaction is going to be slower. Whereas if this value is smaller than directness, don't need to gain ah lot of energy. So they're just going to become activated complexes more. What is the Delta age? That means the n toppy and entropy changes basically the energy difference between the reactant and products. So basically, this value is going to be our delta H.
