Catalysts does not alter the reaction at all but only speeds up the reaction. In an equilibrium reaction it speeds up the rate of reaction in both direction, forward and backward reactions. It actually absorbs the reactant particles into its surface and weakens their bonds. Reaction proceeds when the activation energy is overcomed. In the reactant side, particles collide with each other with high speed.
Catalysts lower the activation energy required for a chemical reaction, allowing reactants to convert into products more easily and quickly. They provide an alternative reaction pathway that requires less energy, but they do not alter the overall energy of the reactants or products. By facilitating the reaction, catalysts increase the reaction rate without being consumed in the process.
Catalysts are chemicals that alter the rate of a chemical reaction without being chemically changed themselves . However to alter the rate of the reaction , the catalysts need to come in contact with the reactant particles. Spreading out the catalyst increases its surface area , hence increases the chances of coming in contact with the reactant particles . So they are able to provide the reactant particles an alternative route with a lower activation energy for the reactant particles to collide and form the product .
Catalysts help chemical reactions: the activation energy is lowered, the reaction rate is accelerated. Catalysts are not exhausted in the reaction and are recyclable.
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
Substances that speed up the rate of reaction are called catalysts. Catalysts participate in chemical reaction but does not get consumed. Yeast is an example of biological catalyst.

In the presence of catalysts the rate of reaction is higher.
Catalysts either accelerate or reduce the rate of the reaction.

Enzymes are not altered in the process of catalyzing chemical transformations. They act as catalysts by lowering the activation energy of a reaction, allowing it to proceed faster, but remain unchanged themselves at the end of the reaction.
