Web(d) Consider the four reaction-energy profile diagrams shown below. (i) Identify the two diagrams that could represent a catalyzed and an uncatalyzed reaction pathway for the same reaction. Indicate which of the two diagrams represents the catalyzed reaction pathway for the reaction. Diagram 1 represents a catalyzed pathway and diagram 2 WebIn a catalysed reaction, the activation energy is at a lower level. This means that less energy is needed for a reaction to take place. More particles are therefore likely to have enough energy for successful collisions to occur. Download Free GCSE Chemistry Notes
