What else can I help you with?
A chemical reaction involving substances a and b stops when b is completely used What would B be?
B would likely be a reactant in the chemical reaction, as it is being completely used up to produce the products of the reaction. It is considered a limiting reactant in this case.
Is a catalyst used up in a reaction?
Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the catalyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.
What is the thing called that is completely used up in a reaction?
The limiting reagent (aka limiting reactant) is the substance which is completely used in a chemical reaction.
What is an example of a chemical change when the starting material is used up?
An example of a chemical change when the starting material is used up is called a complete chemical reaction, at least for the exhausted reactant. That reactant is described as being the limiting reactant because the reaction stops when it is gone even though additional amounts of the other reactant(s) may remain.
The role of catalyst in chemical reaction?
A catalyst speeds up the rate of a chemical reaction.
Why would a chemical reaction stop?
Reactions stop because after time there are less reactants so the chemical reaction starts to slow down. As there are less and less reactants the chemical reaction gets slower and slower until it stops.
Does vinegar and baking soda create a big chemical reaction?
it makes a chemical reaction but not a big one. it just bubbles up and then stops.
A chemical reaction involving substances a and b stops when b is completely used What would B be?
B would likely be a reactant in the chemical reaction, as it is being completely used up to produce the products of the reaction. It is considered a limiting reactant in this case.
Is it true that Enzymes are not consumed during a chemical reaction?
Correct. Enzymes help to speed up chemical reactions. They may speed them up, costing them some energy, but they are never used up.
Element used to speed up chemical reactions?
Anything that is added to a chemical reaction that's intended to speed up the reaction - is a catalyst.
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.
What happens to the reaction as a reactant gets used up?
As a reactant gets used up in a reaction, the rate of the reaction may slow down since there are fewer reactant molecules available to react. This can lead to a decrease in the production of products until all the reactant is fully consumed.
Is a catalyst used up in a reaction?
Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the catalyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.
What can a chemical reaction be speeded up by?
A catalyst can speed up a chemical reaction.
What do enzymes to do a chemical reaction?
Enzymes are catalysts in a chemical reaction, they are used in chemistry to increase the speed of a specific chemical reaction. A single enzyme will not speed up multiple chemical reactions, usually it is limited to one reactant.
What can speed up a chemical reaction by decreasing?
chemical reaction
What is chemical reaction in an enzyme?
to speed up a chemical reaction
