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

∙ 14y agoChemical reactions can be accelerated by catalysts, temperature or pressure changes and by physical changes, such as mixing, to bring the reagents into contact with each other more quickly.

Are substrate and catalyse the same thing?
No! A substrate is a reagent in a chemical reaction. Catalyse is the verb form of catalyst; a catalyst is a chemical species that participates in lowering the energy barrier of a chemical reaction and allow a reaction to occur more rapidly. A catalyst is not consumed in a reaction and therefore only a small amount of catalyst is required in any reaction (if required at all), whereas a substrate must be present in the proper stoichiometric amount to allow a reaction to proceed as it is consumed.
What is a substance that helps chemical reactions?
A substance that helps chemical reactions is called a catalyst. It speeds up the rate of a reaction by providing an alternative pathway with lower activation energy. Catalysts are not consumed in the reaction and can be used repeatedly.
Chemical reaction of chalk and sodium carbonate?
any reaction
What is a excess reagent?
In most reactions there are two types of reactant. One of them is completely consumed and the other is only partially consumed. The reactant that is only partially consumed is the excess reactant.
Name for any substance that speeds up the rate of chemical reaction?
A substance that speeds up a chemical reaction is known as a CATALYST.

Is photosynthesis a chemical property?
The energy provided by absorbing light can substitute for the heat energy that usually accelerates chemical reactions. More fundamentally, any endothermic chemical reaction can occur because an increase in entropy compensates for any heat absorbed by the reaction to make the free energy change negative.
What part does heat play in most chemical changes?
Heat usually accelerates any chemical changes
Can rockets accelerate in space?
Yes, rockets can accelerate in space. When the exhaust accelerates away in one direction, the rocket accelerates away in the other, as any reaction is balanced by an equal and opposite reaction.
What is a substance that helps chemical reactions?
A substance that helps chemical reactions is called a catalyst. It speeds up the rate of a reaction by providing an alternative pathway with lower activation energy. Catalysts are not consumed in the reaction and can be used repeatedly.
What are the similarities and difference between enzymes and chemical catalyst?
so the similarity is that they both speed up the reaction and both have special temperatures they best work at the only difference between them is that enzymes are found in humans and are not made by humans on particular purpose,whereas chemical catalysts are made by people and are not naturaly developed
What is any chemical substance formed as the result of a chemical reaction?
A reaction product.
Is there a chemical reaction when a car is dring through rain?
Any chemical reaction.
Why a catalyst is not considered a reactant or product in a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
Chemical reaction of chalk and sodium carbonate?
any reaction
How does a chemical equation show that a chemical reaction has occurred?
A chemical equation shows that chemical reaction has occurred as new substances have been formed from the reagents. A chemical equation has two sides before reaction and after reaction, if there is any change from the before reaction side to the after reaction side, it indicates that a chemical reaction has just occurred.
Is baking soda reacting with vinegar producing a gas a physical or chemical change?
It is a chemical changes, as is any sort of reaction.
