How does adding a catalyst to reaction affect it?
Provided the catalyst is appropriate for the reaction, it will accelerate the reaction. In other words, the reaction will reach equilibrium between reactants and products faster than it would otherwise have done. The catalyst is unchanged, i.e. at the end of the reaction it is in the same chemical state that it was in at the start. In living systems, the catalysts are made by cells and are called enzymes.
Why do you need a catalyst during a enzyme reaction?
A catalyst speeds up the rate of a chemical reaction by lowering the activation energy needed for the reaction to occur. In the case of an enzyme-catalyzed reaction, the enzyme serves as a biological catalyst, allowing the reaction to occur more efficiently and at lower energy levels than it would without the enzyme.
How does catalyst affect the activation energy of chemical reaction?
The presence of a catalyst affects the activation energy of a reaction by lowering the activation energy, helping the reaction go faster and making it so the reaction does not have to use as much energy to fulfill the products.
How is a catalyst represented in a chemical reaction?
A catalyst is represented in a chemical reaction by placing it above the arrow in the reaction equation. This shows that the catalyst is not consumed in the reaction and only speeds up the reaction rate without being permanently changed.
What type of chemical reaction has a constant rate?
A zero-order reaction exhibits a constant rate of reaction, independent of the concentration of the reactants. In these reactions, the rate is typically determined by factors such as temperature or the presence of a catalyst, rather than the concentration of the substances involved. This characteristic is often observed in reactions where a catalyst is saturated, leading to a fixed rate until the catalyst is depleted.
What is Catalyst for chemical reaction?
A catalyst can improve the reaction rate or allows the realization of a chemical reaction with an energy lower than the activation energy.

What accelerates any chemical reaction but is not consumed in the reaction?
A catalyst. There are two types of catalyst: * Homogenous: a catalyst in the same state (i.e. solid, liquid, gas) as the reactants. * Heterogenous: a catalyst in a different state than the reactants

Can function to speed up chemical reactions?
A catalyst functions to speed up a chemical reaction without being used up in the reaction, meaning that a catalyst can be used more than once.
Why a substance that speeds up a chemical reaction without being permanently changed itself?
A Catalyst.From wikipedia: "Catalysis is the process in which the rate of a chemical reaction is increased by means of a chemical substance known as a catalyst. Unlike other reagents that participate in the chemical reaction, a catalyst is not consumed by the reaction itself. The catalyst may participate in multiple chemical transformations."http://en.wikipedia.org/wiki/Catalyst

How do catalyst affect a chemical reaction?
Adding a catalyst will make the reaction happen faster because the catalyst makes the Activation Energy (the energy required for the reaction to take place) to lower. Meaning more molecules can acquire this lower number of energy. A chemical reaction that involves a catalyst is a special type. A catalyst, in a given chemical reaction, is something that is both an input *and* an output of the reaction equation. What that means, practically, is that a small amount of catalyst is enough to process any amount of the other inputs. (More catalyst means that a given amount will be processed faster.)
What is a Catalyst mean in chemistry?
In Biology, a catalyst is a substance which speeds up a chemical reaction, without being changed themselves. Biological catalysts are found in living organisms.
A substance that enables a chemical reaction to proceed under the different conditions than otherwise possible?
Catalyst
What type of chemical reaction has a constant rate?
A zero-order reaction exhibits a constant rate of reaction, independent of the concentration of the reactants. In these reactions, the rate is typically determined by factors such as temperature or the presence of a catalyst, rather than the concentration of the substances involved. This characteristic is often observed in reactions where a catalyst is saturated, leading to a fixed rate until the catalyst is depleted.
