Key Concepts

Catalyst

A catalyst is a substance that increases the rate of a chemical reaction by providing an alternative reaction pathway with a lower activation energy, without being consumed in the process. It speeds up both the forward and reverse reactions in reversible systems while leaving the equilibrium position unchanged.

Activation Energy

Activation energy is the minimum energy required for reactants to collide effectively and form products. Lowering the activation energy through catalysis allows more molecules to have sufficient energy to overcome the barrier, thereby increasing the reaction rate.

Reaction Mechanism

A reaction mechanism is the detailed sequence of elementary steps that describe how a chemical reaction proceeds from reactants to products. Catalysts work by altering the mechanism, typically by offering a pathway with a lower activation energy, which accelerates the overall rate of the reaction.

Chemical Equilibrium in Reversible Reactions

In reversible reactions, equilibrium occurs when the forward and reverse reaction rates are equal. While catalysts increase the rate at which equilibrium is reached by lowering the activation energies for both directions, they do not alter the equilibrium constant or shift the equilibrium position.
