What is a substance that alters the rate of a chemical reaction without being permanently changed in the reaction?
These are called catalysts.
What else can I help you with?
What is the substance that alters the rate of a chemical reaction without being permanently changed in the reaction?
These are called catalysts.
What is a substance that speeds up a chemical reaction without permanently being changed itself?
A catalyst is a substance that speeds up a chemical reaction by lowering the activation energy needed for the reaction to occur, without being consumed or permanently altered in the process.
When a substance has the ability to participate in a chemical reaction what is it called?
It is called a reactant. While catalysts participate in reaction dynamics, they are not permanently changed in the process.
Are enzymes permanently changed in the chemical reactions they are involved in?
No. Enzymes are not permanently changed in the chemical reactions in which they are involved. After the reaction, they regain their original shape and are free to catalyze another of the same reaction.
What is a substance that is changed in a chemical reaction Called?
A substance that undergoes change in a chemical reaction is called a reactant.
What is A substance that accelerates any chemical reaction but is not consumed in the reaction is a .?
A substance that accelerates a chemical reaction but is not consumed in the process is called a catalyst. Catalysts work by lowering the activation energy required for a reaction to proceed, thus speeding up the reaction without being permanently changed or used up themselves.
Are enzymes permanently changed in the chemical reactions they aer involved in?
No. Enzymes are not permanently changed in the chemical reactions in which they are involved. After the reaction, they regain their original shape and are free to catalyze another of the same reaction.
Why a substance that speeds up a chemical reaction without being permanently changed itself?
A Catalyst.From wikipedia: "Catalysis is the process in which the rate of a chemical reaction is increased by means of a chemical substance known as a catalyst. Unlike other reagents that participate in the chemical reaction, a catalyst is not consumed by the reaction itself. The catalyst may participate in multiple chemical transformations."http://en.wikipedia.org/wiki/Catalyst
What is the term for a substance that speeds up chemical reactions but is not used up or permanently changed?
A catalyst speeds up reactions by lowering the activation energy required for the reaction to occur. The concentration of the catalyst does not change and it is neither part of the reactants nor products; it is an intermediate.
The substances that are produced in a chemical change are called?
chemical reaction is when a substance is changed chemicaly but not physicaly
What is the term for the substance changed during a chemical reaction?
You think probable to the reactants.
What are products reactants and catalysts?
* Reactants: the initial compounds in a chemical reaction. * Products: the final compounds in a chemical reaction. * Catalyst: a chemical compound which help the chemical reaction but not react with the other compounds.
