![Typical Chemical Potential Energy (PE) Diagram for an Exothermic Reaction
A catalyst provides an alternate
pathway for a reaction to occur. The
alternate pathway has a lower
activation energy (AE), meaning that
the reactant molecules do not need to
collide with as much energy in order
for a reaction to occur, so more
collisions result in a reaction, so the
reaction rate is faster.
