Catalysts lower the activation energy required for a chemical reaction. Activation energy refers to the mininum amount of energy that the reactant particles must possess so that effective collisions between them (hence a chemical reaction) can occur.
Because catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction increases.
Enzyme will reduce the activation energy of the reaction, thereby the speed of the reaction increases or acting as a catalyst.
The use of a catalyst increases the chance of particles meeting. This causes there to be a decrease in activation energy, and results in an increase in rate of reaction.
The speed of a chemical reaction may increase or decrease by the addition of a catalyst. In the synthesis of ammonia by Haber's process , Fe + Mo mixture acts as a catalyst which increases the formation of ammonia,here Fe + Mo mixture is positive catalyst(increases the speed of the reaction). The oxidation of chloroform (CHCl3) by air in presence of sunlight is retorted by the edition of 1% ethyl alcohol in to it. Here alcohol acts as a negative catalyst (decreases the speed of the reaction)to the oxidation of chloroform .
A catalyst alters (usually increases) the speed of a chemical reaction in which there is no net change in the amount of catalyst present after reaction is complete.
Because catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction increases.
A catalyst enables more particles to reach the activation energy and to take part in the reaction. Therefore the speed of the reaction increases.
Enzyme will reduce the activation energy of the reaction, thereby the speed of the reaction increases or acting as a catalyst.
Catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction (or the rate of the reaction) increases.

A catalyst can speed up the rate of a given chemical reaction by lowering the activation energy required for the reaction to occur. However, the catalyst does not change the total free energy from reactants to products.
Adding a catalyst to a chemical reaction can increase the rate of the reaction by providing an alternative pathway with lower activation energy. This allows the reaction to occur more quickly without being consumed in the process. Essentially, a catalyst speeds up the reaction without being permanently changed itself.
