What Do Reaction Profiles Show

A reaction profile shows how the energy of the reactants and products changes during a reaction. It includes the activation energy , the minimum energy needed for a reaction to start.

How does a reaction profile show a reaction is exothermic?

An energy level diagram shows whether a reaction is exothermic or endothermic . It shows the energy in the reactants and products , and the difference in energy between them.

How do the reaction profiles show that using a catalyst?

The effect of catalysts A catalyst allows an alternative reaction pathway that has a lower activation energy than the uncatalysed reaction. This is seen in the reaction profile as a lower ‘hump’ representing the activation energy.
