Q:What is the nature of the chemical catalyst?
Different reactions have different catalysts, mainly catalyzed, to speed up the reaction rate
Q:Pls help me define a 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 provides an alternative route of reaction where the activation energy is lower than the original chemical reaction. Catalysts participate in reactions but are neither reactants nor products of the reaction they catalyze. An exception is the process of autocatalysis where the product of a reaction helps to accelerate the same reaction. They work by providing an alternative pathway for the reaction to occur, thus reducing the activation energy and increasing the reaction rate. More generally, one may at times call anything that accelerates a reaction, without itself being consumed or changed, a catalyst (for example, a catalyst for political change). A good example of a catalyst is in the disproportionation of hydrogen peroxide. Hydrogen peroxide reacts to give water and oxygen gas by itself: 2 H2O2 → 2 H2O + O2 Usually, this reaction is slow. On the addition of manganese dioxide to a dilute solution of hydrogen peroxide, an effervescence is observed, and much oxygen, detectable by a glowing splint, is evolved. The manganese dioxide may be recovered, and re-used indefinitely, thus it is a catalyst — it is not consumed by the reaction. A promoter is an accelerator of catalysis, but not a catalyst by itself. An inhibitor inhibits the working of a catalyst.
Q:Chemical reactions in the presence of impurities will cause catalyst poisoning
Catalyst poisoning reaction of raw materials contained in the trace impurities to the catalyst activity, selectivity significantly decreased or lost phenomenon. The nature of the poisoning phenomenon is a trace of impurities and the catalytic activity of the center of a chemical effect, the formation of non-active species. In the gas-solid heterogeneous catalytic reaction is formed in the adsorption complex. One is that if the toxic and active components of the role of weak, can be a simple way to restore the activity, known as reversible poisoning or temporary poisoning. The other is irreversible poisoning, it is impossible to restore the activity in a simple way. In order to reduce the side reaction activity, it is sometimes necessary to allow the catalyst to be selected for poisoning.
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:What is the difference between biological and chemical catalysts?
Biological catalysis involves an enzyme usually working in conjunction with a co-enzyme. These enzyme/co-enzyme systems are highly specific and are usually only effective for one reaction. Catalysis of non biological reactions is usually much more general and any one catalyst will be effective in many reactions.
Q:Effect of Catalyst on Chemical Reaction Rate
The catalyst can only change the rate of chemical change (faster or slower), does not change its own quality and chemical properties, nor does it change the amount of reaction product.
Q:About the catalyst?
Catalysts are not used/destroyed in any reactions, it merely speeds up the process by lowering the reaction activation energy. It functions by being able to weaken or break the required bonds necessary in the chemical reaction (thus lowering activation energy) through temporary and weak bonding to form a complex. In this case the H2O2 molecule will bind with the MnO2 molecule due to the complimentary sites (thus forming a complex) to weaken the bonds for decomposition, but after decomposition the products (oxygen and water molecules) break off from the catalyst (as there are no more complementary sites with them) thus the catalyst will not be destroyed.
Q:Does a catalyst have an effect on the Gibbs free energy of a reaction?
A catalyst can change the activation energy not the Gibbs energy. The Gibbs energy is the energy difference between the initial state and final state. A catalyst cannot change that. Imagine you are driving from school to home. How you drive do not change the height difference between the school and your home. However, a catalyst can change your path which can change the routine you drive from school to home. So if there is a hill in between your school and you home, you have the choice to drive through it or drive around. Here is a picture: upload.wikimedia.org/wikipedia/co... A catalyst can change the height of the barrier, but cannot alter the initial or final state.
Q:What is the relationship between the catalyst and the chemical reaction?
Catalytic, also known as catalyst, is defined in the junior high school stage to be able to change the rate of chemical reactions, and its own quality, composition and chemical properties remain constant before and after chemical reactions. For example, manganese dioxide can be used as hydrogen peroxide (hydrogen peroxide) decomposition of the catalyst. The catalyst is divided into the positive catalyst and the catalyst is used. The positive catalyst contributes to the reaction to move in the positive direction, and the reverse catalyst contributes to the reaction to move in the reverse direction.
Q:What is the PTC catalyst in chemistry?
1, polyether chain polyethylene glycol: H (OCH2CH2) nOH chain polyethylene glycol dialkyl ether: R (OCH2CH2) nOR2, cyclic crown ethers: 18 crown 6,15 crown 5, Fine and so on. 3, quaternary ammonium salt: commonly used quaternary ammonium salt phase transfer catalyst is benzyl triethyl ammonium chloride (TEBA), tetrabutyl ammonium bromide, tetrabutylammonium chloride, tetrabutylammonium hydrogen sulfate (TBAB) , Trioctylmethylammonium chloride, dodecyltrimethylammonium chloride, tetradecyltrimethylammonium chloride, and the like. 4, tertiary amine: R4N X, pyridine, tributylamine and the like. 5, quaternary ammonium base (its alkaline and sodium hydroxide similar) soluble in water, strong hygroscopicity. 6, quaternary phosphonium
