Key Concepts

Catalysis

Catalysis refers to the acceleration of a chemical reaction by a catalyst, a substance that facilitates the reaction without being consumed. Catalysts provide alternative reaction mechanisms with lower activation energies, enhancing the overall rate of the process.

Reaction Rate

Reaction rate is a measure of how quickly reactants are converted into products. By lowering the activation energy through mechanisms such as adsorption, catalysts increase the speed at which reactions occur, making processes more efficient.

Adsorption Theory

Adsorption theory in catalysis involves the process by which reactant molecules adhere to the surface of a catalyst. This adherence can alter the chemical environment of the reactants, leading to the weakening of bonds and creating an alternate reaction pathway that requires less energy.

Activation Energy

Activation energy is the minimum energy required for reactants to transform into products. In catalysis, the reduction of activation energy is crucial because it allows a greater number of molecules to participate in the reaction at a given temperature, thereby increasing the reaction rate.
