- Q:what is a catalyst?
- Somthing that helps to speed things up. example: an enzyme is a biological catalyst, it speeds things up
- Q:What is the superiority of the catalyst compared to the stoichiometric reagent?
- Efficient: The catalytic efficiency of the enzyme is higher than that of the inorganic catalyst, making the reaction rate faster;
- Q:Will the catalyst in the chemical reaction be reduced?
- The amount of catalyst in the chemical reaction is not reduced, the catalyst is divided into a positive catalyst and a negative catalyst, the positive catalyst promotes the reaction, and the negative catalyst inhibits the reaction
- Q:It is best to tell me what the role of sulfuric acid in these reactions, respectively
- Esterification reaction (dehydration), nitration (dehydration, concentrated nitric acid), carbonation reaction or dehydration reaction (organic matter in sulfuric acid blackening, dehydrating agent), sulfonation reaction (dehydrating agent), ethylene (dehydrating agent).
- 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:Chemical questions: "CO2 and H2 in the catalyst conditions have a reaction, the reaction of the chemical equation is"
- CO2 + H2 = CO + H2O (conditions: catalyst, generally already heating, and reversible)
- Q:Why the catalyst is required to have a large surface area and a rich pore structure
- Chemical reactions are generally contact reaction, of course, the more contact with the faster response, pore structure is to increase the contact area
- Q:Brief introduction of enzyme as biocatalyst and general chemical catalyst and its personality
- enzyme inactivation (4) enzyme activity can be timely and effective regulation (5) the role of the enzyme conditions are more moderate (6) most of the enzyme (1) the catalytic efficiency is very high (2) Of the catalytic activity is often associated with coenzymes, auxiliary or metal ions, and some enzyme activity also need RNA as a cofactor Caixing, such as telomerase
- Q:Characteristics and types of catalysts?
- Catalysts don't undergo any change. and types of catalysts - 1) Homogeneous Catalysts ( Having same phase that of reactant, product i.e. reactant and product and catalysts all are either liquid or gas or solid.). 2) Hetrogenrous Catalysts (Different Phase than that of reactant and product. 3) Autocatalysts (reaction proceed catalysed as product is formed or product catalyse the reaction.)
