The catalyst is not a reactant in a chemical reaction but contribute to the success of this reaction.
What else can I help you with?
A catalyst for automobile exhausts removes carbon dioxide. True or False?
that is true
Is it true that catalyst speed chemical reactions but are not changed by them?
Yes, it's true.
Is it true that reactants of a catalyst assisted reaction are known as substrates?
Yes. it is true.
What is ture of a catalyst?
It is true that a catalyst is used in chemical reactions to help speed up the reaction by reducing activation energy.
Is it true that the effect of a catalyst on a reaction is to raise the activation energy?
No, it is not true that a catalyst raises the activation energy of a reaction. In fact, a catalyst lowers the activation energy, allowing the reaction to occur more easily and at a faster rate. By providing an alternative pathway for the reaction, catalysts facilitate the formation of products without being consumed in the process.
What causes molecules to change?
I think this refers to catalysts as these are considered not to be changed by a reaction-- sometimes this true when molecules react on the surface of a catalyst bu sometimes the catalyst does get involved in the chemical reaction- but is regenerated.
CFCs are the catalyst in the destruction of Ozone. true or false?
CFC's are catalysts. They fasten the rate of reaction.
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 does a catalyst do in a chemical reaction?
Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.
What isn't true of a catalyst?
A catalyst does not alter the equilibrium of a chemical reaction; it only accelerates the rate at which equilibrium is reached. Additionally, a catalyst is not consumed in the reaction, meaning it can be used repeatedly. Furthermore, it does not change the overall energy change (enthalpy) of the reaction; it merely provides an alternative pathway with a lower activation energy.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
What happens to a catalyst after a reaction?
In any reaction, a catalyst is never used up or changed. This means that at the end of every reaction you should always get your catalyst back. sometimes in the course of the reaction, the catalyst is used up, but by the end of the reaction it will always be reformed completely.
