Q:Chemical "catalyst can speed up the chemical reaction rate of other substances," this sentence right?

Wrong, the catalyst is divided into two kinds, one is to speed up the chemical reaction speed, and the other is the opposite

What connections link the two books? How is food used in this book? Why don't we learn more about the life of Teri Litch (hint: examine the book's POV) How is Kate's relationship with her father? Why is it that way? Does it change over the course of the book. (Give examples for each answer.) Discuss the role of religion in this book. What does Kate believe in? Teri? Mitchell? How and why does Kate's relationship with Teri change after Mikey's death? Why are the three sections of the book labeled Solid, Liquid and Gas? Who is the most important character in this book? Why? How do the characters in Catalyst deal with defeat?

Q:Could God be Discribed as a Catalyst?

On reflection, I would say no, God can't be described as a catalyst. That would be like calling a farmer who fertilizes his crop a catalyst; whereas it's the fertilizer that is the catalyst. Or it would be like a scientist in a lab adding an enzyme to something to speed a process; and then having us label the scientist as the catalyst. So in the same way, God doesn't seem to be the actual catalyst; maybe the spirit is the catalyst....

Q:Chemical catalyst system baa?

Can speed up or slow down the reaction rate without participating in the reaction of the material

Q:The best use of chemical catalysts

Do not know what you want to use the best thing is what the catalyst is generally used in the process, there will be an initial induction period, the catalytic activity is relatively low, and then reached a stable catalytic state, this paragraph is generally called the catalyst life, the final Due to poisoning, active ingredient aggregation and so on factors, the catalyst activity will be reduced, then need to replace the new catalyst

Q:I need to name 3everyday catalysts for my chemistry homework. I don't want anything complicated there must just be 3 easy ones out there... Then could you please state what each one is used for? Please do it like this, e.g.Hello ; used to say hi to someone. I know that's a bad example but please!!

Hello ; Chemical catalysts are substances that increase the rate of reaction (while remaining themselves chemically unchanged: Polyethylene, the polymer used to make everything from: 1. garbage bags and 2. grocery bags, to 3. squeezable bottles, to 4. cable insulation, is made by passing ethylene gas over a catalyst. Most other polymers are made in the same (or similar) way. Synthetic rubber, nylon, polyester, PVC, teflon, etc. It's not hard to think of 10 uses for these catalyst-produced materials alone... e.g. : 5. rain coats 6. pantyhose 7. water pipes 8. bouncy balls 9. non-stick surfaces and pads 10. saran wrap 11. food containers 12. cell-phone and laptop cases 13. cheap wigs 14. fishing line... 15. Enzymes are Biological catalysts: 16. beer and 17. bread are typically made with yeast, a living organism containing enzymes I hope this helps!

Q:What kind of compounds or elements can be used as catalysts in high school chemistry? What is the catalyst for what?

High school is the most common is manganese dioxide, and potassium permanganate heating oxygen, hydrogen peroxide decomposition are used, which is inferred in the problem there is a lot of

Q:Is the chemical reaction rate constant related to the amount of catalyst used?

The catalyst has a certain amount of suitable range, the general factory production of some substances (such as ammonia), the amount of catalyst used is limited, to achieve a value after no greater role. So the reaction rate constant is independent of the amount of catalyst used

Q:Just something I've always wondered about...

transition okorder /... for ex-- X (one reactant) + catalyst(transition element) ------X.catalyst(intermediate unstable compound) X.catalyst + Y (other reactant) --------XY(product) + catalyst how the change in oxidation state of transition elements helps the reacton through the formation of intermediates may be seen from reaction in between SO2 and O2 to form SO3 in presence of V2O5 ... V2O5 + SO2 ------V2O4 + SO3 2V2O4 + O2 ------2V2O5 in the above reaction vanadium changes its oxidation state from +5 to +4 and again to +5.. another example is reaction in between iodide and persulphate ions in presence of Fe(III) as catalyst... 2I(-) + S2O8(2-) ---------I2 + 2SO4(2-) (Fe(III) is present as catalyst) the reaction is believed to take place as follows: 2Fe(3+) + 2I(-) ------2Fe(2+) + I2 2Fe(2+) + S2O8(2-) ------2Fe(3+) + 2SO4(2-) (3)in number of cases transition elements provide a suitable large surface area with free valencies on which reactants are absorbed ...as a result concentration of reactants on surface of catalysts increases..hence rate of reaction increases...this is known as adsorption theory.... according to adsorption theory : there are free valencies on surface of solid transition metals because of the incomplete d-subshelll.. so the mechanism of catalysis involve followin five steps: (1) diffusion of reactant molecules towards surface of catalyst... (2) adsorption of reactant molecules on surface of catalyst by forming loose bonds with catalyst due to free valencies... (3)occurence of chemical reactions between reactant and catalyst forming an intermediate.. (4)desorption of product molecules from surface due to its lack of affinity for the catalyst surface thereby making the surface free for fresh adsorption of reactant molecules... (5)diffusion of product molecules away from surface of catalyst...

Q:Does all chemical reactions have a catalyst?

Not some reaction without catalyst
