Catalysts are substances that speed up chemical reaction without themselves being chemically changed.A catalyst provides an alternative reaction pathway with lower activation energy. Catalysts do not affect the enthalpy change of reactions. At any given temperature, more molecules will have greater than or equal to the activation energy as the activation energy is lower.
