Hope this helps
Explanation:
Potential energy diagrams represent the energy transfer in chemical reactions  in a diagram called a potential energy graph and/or a reaction progress curve. A potential energy diagram shows the adjustment in potential energy of a system as reactants are changed.

Answer:
<em>What quantity dictates the speed of a reaction?</em> The activation energy
Explanation:
According to the collision theory, when molecules collide, they must overcome an energy barrier for the reaction to take place. This energy, known as activation energy, is represented by the difference in energy between the initial state and the transition state. The higher the activation energy, the slower the reaction. That's why catalysts reduce the activation energy to accelerate the reaction.
