Catalysts are substances that increase the rate of a chemical reaction without being consumed in the process. They work by lowering the activation energy needed for the reaction to proceed.
5 Must Know Facts For Your Next Test
Catalysts lower the activation energy required for a reaction, making it easier for reactants to convert into products.
Catalysts do not alter the equilibrium position of a chemical reaction; they only help reach equilibrium faster.
Heterogeneous catalysts exist in a different phase than the reactants, while homogeneous catalysts exist in the same phase as the reactants.
Enzymes are biological catalysts that speed up biochemical reactions in living organisms.
A catalyst can be poisoned by impurities, which decreases its effectiveness and requires specific conditions for optimal performance.
