Catalysis

Definition

Catalysis is the process of increasing the rate of a chemical reaction by adding a substance called a catalyst, which is not consumed during the reaction. This process plays a critical role in scientific computing by allowing simulations and models to efficiently explore complex chemical reactions and their dynamics. In many emerging applications, catalysis is used to optimize reactions in various fields, such as material science, pharmaceuticals, and renewable energy.
