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.
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.
Which of these would be expected to increase the rate of sa chemical reaction?
an enzyme or other catalyst
What is the substance that speeds up chemical reaction without harming itself?
That would be a catalyst.
What makes chemical reaction to go faster?
cofee or nos or an energy drink would speed up a chemical reaction..
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).
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.
What is the purpose of a catalyst?
a catalyst provides a different path for a reaction to occur To lower the activation energy of a reaction
What is a substance that speeds up the chemical reaction pernmanently changing?
Catalyst. Biological catalysts would be enzymes.
Protein molecule that can speed up a chemical reaction?
That would be an enzyme. Also know as a biological Catalyst
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.
What effect would a catalyst have on the reaction A2 plus 2B ---- 2AB?
A catalyst would lead to the reaction being quicker.
