A substance that accelerates the rate of a chemical reaction is called a catalyst.
A substance that accelerates a chemical reaction is called a catalyst. Catalysts work by lowering the activation energy needed for a reaction to occur, which speeds up the reaction without being consumed in the process.
The rate of chemical reactions is how long a chemical reaction takes to finish.
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.
The chemical term is reaction rate.
A lot of agents can affect heart rate, but let's say... Cocaine (accelerates the heart rate) Adrenaline (accelerates the heart rate) Potassium chloride (reduces it to zero - this is the chemical they use in executions to make the heart stop)
The first-order reaction formula used to determine the rate of a chemical reaction is: Rate kA, where Rate is the reaction rate, k is the rate constant, and A is the concentration of the reactant.
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
Yes, the rate constant can change with concentration in a chemical reaction.
A catalyst is a substance that accelerates or increases the rate of a chemical reaction. In principle a catalyst should remain unaffected during the process. However normally it loses some activity during it resuses.
