What effect would a catalyst have on the reaction A2 plus 2B ---- 2AB?
A catalyst would lead to the reaction being quicker.
What is the effect of the addition of a catalyst on the rate of a chemical reaction?
A catalyst decreases the activation energy of a chemical reaction.
Which would increases the reaction rate?
Temperature
What does a catalyst do to the rate of a chemical reaction?
A catalyst is a substance that speeds up the rate of a chemical reaction without changing the substance. It does this by reducing the minimal reaction energy. A catalyst is not used up in a reaction therefore they last indefinitely.
What is an organic catalyst?
A catalyst for an organic chemistry reaction would be any substance that speeds up the reaction. This would include metals such as platinum, palladium, mercury, zinc, and even certain acids. It must be noted that the catalyst varies for every reaction. An organically based catalyst (a catalyst made of carbon) would be an enzyme, coenzyme, or a vitamin. You can be an organic catalyst by being the change you wish to see in the world.

What substance increases the rate of a reaction but is not itself changed by the reaction?
It's called a catalyst. A catalyst is present during a chemical reaction but does not participate as a reactant or product. A catalyst lowers the reaction's activation energy, making the reaction easier to happen. In the equation for a chemical reaction, the catalyst's formula appears in small notation above the "yield" arrow (format won't let me show you an example.) An example of a catalyst is potassium iodide (KI) speeding up the decomposition of hydrogen peroxide (H2O2).
What effect does a promoter catalyst have on the position of the equilibrium?
By definition a catalyst cannot affect equilibrium because although a catalyst can speed up a chemical reaction, it cannot change the thermodynamics of it, and equilibrium is determined solely by thermodynamics. A catalyst may help a system reach equilibrium more quickly, but it will not change it. One possible way a catalyst could affect equilibrium is by introducing a catalyst that affects a different reaction involving the substrate or products of the original reaction, but this would be cheating since the system would no longer be closed.
When a catalyst is added to a reaction?
There are positive catalysts used when the reaction rate is needed to be faster or the negative catalysts to make the reaction rate slower.
How would the equilibrium concentration of H2O be affected by adding a catalyst to the mixture?
None. A catalyst affects only the rate of reaction, and if the reaction is already at equilibrium, the net rate of the reaction is zero and remains so after a catalyst is added.
How would you speed up a reaction without a catalyst?
heat the vessel the reaction is taking place!
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 would a catalyst be needed for a chemical reaction?
lower activation energy, make the reaction more economical
