- Q: High school knowledge __ teacher do not know right!
- Nothing to do, but with the percentage of activated molecules, is proportional to
- Q: The addition of the catalyst has no effect on the chemical equilibrium of the movement
- Hello, the essence of chemical equilibrium is a dynamic equilibrium, under certain conditions, the equilibrium constant of the reaction is a certain value, the role of the catalyst is to reduce the activation energy required for the reaction, increase the number of activated molecules, so that the reaction within a unit time The number of molecules increased, but the positive reaction is positive for the reaction, so do not change the speed
- Q: High school chemistry, catalyst activation energy map
- Catalytic reaction is the reaction of the first reaction with the catalyst or attached to the catalyst to form intermediates, and then further reaction to produce products and catalysts, so the amount of catalyst in theory is the same! The activation of these two processes can be reduced! So there will be two peaks! Can be simplified as a peak!
- Q: How does catalyst aid a chemical reaction?
- it makes the reaction go faster.
- Q: How do I write about the ion equation?
- 4NH3 + 5O2 == 4NO + 6H2O
- Q: What is the microcosmic principle of the catalytic reaction in the chemical reaction?
- The catalyst reduces the activation rate of the reactants by increasing the reactant density of the reaction conditions and making the chemical reaction easier.
- Q: Explain how a catalyst may increase the rate of chemical reaction?
- A catalyst lowers the activation energy of a reaction without affecting the reaction in any way.
- Q: Junior high school chemistry - chemical reaction before and after the quality and chemical properties of the material must be the catalyst?
- It is not always possible that the equivalent reaction, i.e. one or more of the reactants, is the same as the relative atomic mass of one or more of the products and the coefficients in the chemical equation are the same
- Q: What is a chemical catalyst?
- A substance that participates in chemical reactions but does not change the quality and chemical properties. It can change the reactant activation energy, speed up or slow down the reaction rate.
- 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!
