- Q: High school knowledge __ teacher do not know right!
- Nothing to do, but with the percentage of activated molecules, is proportional to
- Q: What is the similarity between enzymes and general chemical catalysts?
- (1) The enzyme is the same in many respects as a biocatalyst and a general catalyst, such as a small amount and a high catalytic efficiency. As with the general catalyst, the enzyme can only change the rate of chemical reaction and does not change the equilibrium of the chemical reaction It is possible to catalyze the activation of a large number of substrates in a short time and to reflect the high efficiency of enzyme catalysis.The enzyme can reduce the activation energy of the reaction (activation) (△ G) during the reaction, but the reaction rate is accelerated and the reaction time is reduced, but the equilibrium constant is not changed. (2) However, the enzyme is a biological macromolecule (1) Enzyme-catalyzed high efficiency: The catalytic effect of the catalyst can increase the reaction rate by 10 ^ 6 ~ 10 ^ 12 times, which is at least several times higher than that of the conventional catalyst. (2) The enzyme catalyst Highly specificity: including specificity of response, substrate specificity, chirality specificity, geometric specificity, etc., that an enzyme can only act on a certain class or a specific substance. Bond, ester bond, peptide bond and so on can be catalyzed by acid-base hydrolysis, but the hydrolysis of these chemical bonds are different, respectively, the corresponding glycosidase, esterase and peptidase, that is, they were specific (3) enzymatic reaction conditions are mild: enzymatic reaction is generally carried out in aqueous solution of pH = 5 ~ 8, the reaction temperature range is 20 ~ 40 ℃
- 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.)
- Q: Could you tell me all the differences between those two catalysts? Thank you very much.
- One occurs in biological systems and the other is in chemical reactions. Biological catalysts are basically enzymes - proteins which regulate biochemical reactions whilst chemical catalysts act on non-biological chemical reactions and are inorganic elements or compounds.
- Q: pls give one or two catalysts that are used in the industry for example:Rhodium catalyst in a catalytic converter of a car or the Iron catalyst for making ammoniaTHANKS :)
- u . s . a . of america has an excellent style of organic gas. In theory that's accessible to have an electric powered motor force a compressor to take the low stress gas to make it dense adequate to get adequate interior the vehicle to run for a mutually as (in actuality, gas stations with organic gas pumps do it precisely like that, that's no longer trucked to them, we've a pair in Dallas) the real undertaking is that, specific it will be pressurized, requiring a greater perfect tank than propane, that's a liquid interior the tank, and the tank must be a cumbersome cylinder for capability or numerous smaller cylinders area by making use of area. Getting this into the physique of the vehicle devoid of doing away with all the storage/bags area isn't ordinary. And ultimate efforts nevertheless finally end up with the miles in line with fill up being decrease than the gas which inserts in a small area.
- Q: Will the chemical catalyst not reduce that?
- Why is it done? Although the catalyst does not react chemically, the catalyst itself is deteriorated and is not always used
- Q: Can a catalyst react with a reactant?
- Exactly no. A catalyst just provides a shortcut to a reaction and thats is by combining with the reactant and at end of reaction it splits from the reactant it combined with.if a catalyst reacts then it is not a catalyst
- Q: The size of △ H in the thermochemical reaction equation is related to the use and unused catalyst
- There is no relationship between the catalyst can only change the reaction rate
- Q: okay im doing a project for my classroom about catalyst and i have to draw a picture but when i looked up on google i just saw a bunch of random stuff and a couple were metal so thats why im asking this question. :)
- a okorder /...
- Q: i keep messing up on those 2 simple things haha i would apprecaite some help.
- enzymes help biochemical reactions proceed at a faster rate than normal in a physiological system, catalysts or sometimes referred to as subunits, metals and other ligands, bind enzymes, and can have a positive and negative effect on the rate of a reaction. search them on wikipedia!
