Do catalysts affect equilibrium concentration

Web-A catalyst is a substance that changes the rate off a chemical reaction without undergoing any permanent change itself. -It is not used up. -It may react with a reactant to form an intermediate or may provide a surface on which the reaction can take place. -At the end of the reaction the catalyst is regenerated. What are the two types of catalyst? WebThe effect of concentration on equilibrium. If the concentration of a substance is changed, the equilibrium will shift to minimise the effect of that change. If the concentration of a reactant reactant is increased the equilibrium will shift in the direction of the reaction that uses the reactants, so that the reactant concentration decreases.
