Why the adsorption strength of the catalyst is an important factor in determining its success?
When reactants are binding to the surface of the catalyst, it is important that the catalyst is strong enough to allow a reaction to take place, however having a strong catalyst could mean that the products could permenantly bind to the catalyst, which is a problem. So if the catalyst is too strong, the catalyst isnt very sucessful, and if it is too weak, it also isn't sucesful.
A catalyst for automobile exhausts removes carbon dioxide. True or False?
that is true
Is it true that reactants of a catalyst assisted reaction are known as substrates?
Yes. it is true.
Is it true that catalyst speed chemical reactions but are not changed by them?
Yes, it's 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 imperfect fungi capable of only sexual reproduction?
it isnt true
Is it true or false catalysts speed chemical reactions but are not changed by them?
True. That's one of the reasons you use them.
True or false is five thousand weeks less than a century?
no it isnt
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.
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.
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.
