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 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 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
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 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
What effect would a catalyst have on the reaction A2 plus 2B ---- 2AB?
A catalyst would lead to the reaction being quicker.
How does adding a catalyst to reaction affect it?
A catalyst increases the rate of a chemical reaction by providing an alternative pathway with lower activation energy. It does not change the equilibrium state or the overall thermodynamics of the reaction. This allows the reaction to proceed faster without being consumed in the process.
What chemicals are used to help break the chemical compounds?
You may be referring to substances that are assuming the role of catalyst in a chemical reaction. A large variety of chemicals do this. I would say, search for the term catalyst in, say, wikipedia for instances.
