what do reaction profiles show?
they show energy changes in a reaction, including the relative energies of reactants and products
what does an exothermic reaction profile show?
the products are at a lower energy than the reactants, and the height difference shows the energy given out
what does the initial rise in an exothermic reaction profile represent?
the activation energy (eª), which is the energy needed to start the reaction
what is activation energy?
the minimum energy reactants need to collide and react
what happens if a reaction has a high activation energy?
more energy is needed to start it, usually supplied by heating
what does an endothermic reaction profile show?
the products are at a higher energy than the reactants, and the height difference shows the energy taken in
