Endothermic and Exothermic Graphs

Postby Mariana Fuentes 4l » Sun Feb 17, 2019 10:24 pm

Can anyone explain to me the difference between these two graphs please?

In both graphs, the x axis should indicate progress of a reaction and the y axis should indicate the energy of a reaction. In an exothermic graph, the products are at a lower energy level than the reactants, because energy is released. In an endothermic graph, the products are at a higher energy level than the reactants because the reaction takes in energy.

We often discuss endothermic and exothermic reactions as absorbing heat and releasing heat, respectively. Heat is a form of energy, which is why energy is on the y axis.

But keep in mind that delta H has a lot to do with this. and when measuring delta H you would measure from the beginning to the end state. (even if it does a big loop up, its just beginning and end result)
