Catalyst and Equilibrium
What is Catalyst and Equilibrium?
The principle that a catalyst increases the rates of the forward and reverse reactions by the same factor, because it lowers the activation energy of both by the same amount. Equilibrium is therefore reached in a shorter time, while the position of equilibrium, the equilibrium yield and the enthalpy change are all unaltered.
This definition is part of the Chemical Reactions chapter in Cambridge O Level Chemistry.
