Q:role of catalyst?
In chemistry and biology, catalysis is the acceleration (increase in rate) of a chemical reaction by means of a substance, called a catalyst, that is itself not consumed by the overall reaction. The word is derived from the Greek noun κατάλυσις, related to the verb καταλύειν, meaning to annul or to untie or to pick up. A catalyst decreases the activation energy of a chemical reaction.
Q:what is the difference between enzyme and catalyst?
Enzymes and catalysts both affect the rate of a reaction. The difference between catalysts and enzymes is that while catalysts are inorganic compounds, enzymes are largely organic in nature and are bio-catalysts. Even though all known enzymes are catalysts, all catalysts are not enzymes. Moreover, catalysts and enzymes are not consumed in the reactions they catalyze. Catalysts are low molecular weight componds, enzymes are high molecular globular proteins. Catalysts are inorganic, enzymes are organic. Catalyst reaction rates are slower (usually) than enzyme reaction rates. Catalysts are not generally specific - enzymes are VERY specific. Catalysts increase or decrease the rate of a chemical reaction, enzymes are proteins that incrase the rate of chemical reactions & convert the substrate into product. There are 2 types of catalysts - (positive & negative), and the 2 types of enzymes are activation enzymes and inhibitory enzymes. Catalysts are simple inorganic molecules, while enzymes are complex proteins.
Q:The quality and nature of the catalyst before and after the chemical reaction did not change this sentence wrong?
The quality and nature of the catalyst are not changed before and after the chemical reaction ... 7604
Q:what is a fuel catalyst?
Fuel catalyst is another name for fuel additive, the companies that make these additives make all kinds of claims how it increases power and reduces emiissions.. blah blah blah. Fuel catalyst is nothing more then a octane booster (gas engines) or cetane booster (diesel engines), it like all the other bogus products are worthless, octane booster will only show an improvement in performance IF the octane level in your current fuel supply is too low, higher octane fuel burns slower then lower octane fuel, that's how it quenches pinging and preignition both of which are caused by incorrect engine design and/or settings. Always use the lowest octane fuel that the engine will tolerate, if you have to pull advance out of the total timing then it needs more octane to run full timing and make max power, the only thing you can do to improve the quality of fuel in your tank is add a stabililizing additive such as (Stabil), it treats the fuel and prevents it from going stale or turning to varnish, it's especially useful when the vehicle is parked for long periods with fuel in the tank and carburetor, normally after a month or two of being parked the fuel in the carb turns to varnish and clogs the jets, with Stabil the fuel doesn't change composition.
Q:NH3 and O2 in the presence of catalyst in the chemical reaction occurred how to write,
4NH3 + 5O2 == 4NO + 6H2O
Q:catalyst..........?
Sort of. If the reaction is under aqueous conditions (any water is included in the reaction), then yes, H+ = H3O+. This is because free protons present (H+) will be coordinated generally to molecules of water [thus H2O + H+ =H3O+ ]. But there are reaction conditions where water is not present, but an acid catalyst is still possible. In these cases, the acid catalyst may frequently be indicated as simply H+. Either way, the function in most of your reaction mechanisms is basically the same, whether indicated as H+ or H3O+ -- and that's to protonate molecules (Lewis or Bronsted bases) with H+. Concentrated sulfuric acid would be an example of a mostly-anhydrous (no water) strong proton/acid source (H+). Hydrochloric acid (HCl) frequently is available as an aqueous solution, even concentrated HCl is an aqueous solution of HCl. HCl itself is a gas under ambient conditions... but it has solubility in water and thus is conveniently sold frequently as an aqueous solution (which could be represented as H3O+)
Q:Chemical common sense about the catalyst
Has a large surface area, is the reactants and catalyst contact more fully, improve the catalytic effect
Q:The chemical equation of heating reaction of benzene and hydrogen under the action of catalyst
C6H6 benzene + 3H2 - (arrow) C6H12 cyclohexane (Ni catalytic heating)
Q:Why are transition metals more likely to be catalysts?
activation energy has got nothing to do with this. the main reason that the transition metal oxides are catalysts is that they have vacant d orbitals. the reagents are adsorbed on the metal surface and the d orbitals serve as a sort of clamp between the substrates and reagents. for example if you consider the hydrogenation of ethylene in palladium catalyst here the d orbitals lead to syn addition of hydrogen by clamping the pi electron cloud . this is a sort of chemisorption.
Q:What are the catalysts that appear in the chemistry experiment?
Hydrogen peroxide, manganese dioxide
