Q:Question about catalysts?
Generally, catalysts participate and facilitate a reaction, but the catalyst is returned unchanged. For example, sulfuric acid may be used in a Fischer esterification, palladium in a Heck reaction, pyridine in an acylation reaction, hydroxide in an aldol condensation, cyanide in a benzoin condensation, etc. An enzyme can facilitate a reaction is a similar manner, by being an acid or base catalyst for example. We could say that generally, reactions are reversible. Practically, that is not true as the energy differences of the reactants and products may be so different to prevent the reverse, an explosion for example. If a reaction is reversible, that may not mean the reverse reaction will take place. Le Chatelier's Principle can apply to determine the products.
Q:On the issue of chemical balance and catalyst
The catalyst also changes the forward and reverse reaction rate.
Q:What reactions need catalysts?
Reactions that have high Activation Energy need catalysts to speed up reactions. These reactions aren't spontaneous since the reactants do not have enough energy to overcome the activation energy barrier. Catalysts are compounds that speed up reactions by providing an alternative pathway for the reaction. It is a common misconception that catalysts lower the activation energy. It doesn't actually lower the activation energy, instead it provides an alternative pathway with lower activation energy. For example, breakdown of hydrogen peroxide happens in nature but, relatively slowly. When you add a little bit of manganese dioxide, the breakdown happens a lot faster. Another example is, breakdown of glucose in the body. It is facilitated by an enzyme called amylase (or carbohydrase). An industrial example is the use of vanadium pentoxide (V2O5) in the Contact process, where SO2 is converted to SO3 in the presence of V2O5. Hope that helps!
Q:What is the difference between biological enzymes and chemical catalysts?
The biological enzyme is a class of molecules with moderate molecular weight in the living cells. It is a natural macromolecule catalyst in nature because the enzyme and the reactants are more specific than the reaction of the catalyst with the chemical synthesis of the catalyst (1) High efficiency (2) selectivity good by-product less (3) mild reaction conditions and so on
Q:When there is a catalyst in the chemical equation, it is not necessary to match the atoms of the catalyst
The habit of writing is not to write the catalyst involved in the equation, it is usually written in the equation above the equal or below
Q:What is the relationship between the catalyst and the chemical reaction?
Enzyme is a biocatalytic biological biomolecule, a biocatalyst that accelerates the rate of biochemical reactions without changing the direction and product of the reaction. That is, enzymes can only be used to change the speed of various biochemical reactions, but not the biochemical reaction itself. Enzyme is a kind of amino acid composed of a special biological activity of the substance, which exists in all live animals and plants, is to maintain the normal function of the body, digest food, repair tissue and other life activities of a necessary material.
Q:Can a catalyst be present in the rate equation?
There are many reactions that would not happen to any extent without a catalyst, yet I have never seen a rate equation that included a catalyst. For example, the Haber reaction requires a catalyst, but the rate equation for it does not include a catalyst. If a reaction will work without a catalyst, you can find its rate under this condition. Then if you run the same reaction with a catalyst you will get a different rate of reaction but the catalyst concentration does not show up in the Rate law for that reaction.
Q:Chemical catalyst in several ways
Some are composed of oxidative - reduced electricity, such as manganese dioxide catalyzed by hydrogen peroxide decomposition
Q:Gene cloning of heat - resistant bacteria
The process of metabolism in the body contains many complex and regular material metabolism and energy changes.Green plants and certain bacteria use solar energy, water, CO2 and inorganic salts and other simple substances, after a series of changes, the synthesis of complex sugar, Fat, protein and other macromolecules, and animals and the use of these plants in the material, and through the complex decomposition and synthesis, the reaction into their own part of the need to grow, breeding, etc. In the laboratory, complex The synthesis and decomposition of organic matter must be carried out under severe conditions such as high temperature, high pressure, strong acid and alkali, such as starch and protein hydrolysis, and some reactions are difficult to carry out in vitro, such as protein synthesis, but in biological conditions Mild (370C or so, near neutral pH), these reactions can be carried out smoothly and quickly.For example, animals eat meat in the digestive tract only a few hours will be completely digested and decomposed; bacteria in the appropriate conditions, Twenty minutes to proliferate generation, in this short twenty minutes, the synthesis of new cells within the need for all the complex substances, etc., what is the reason? This makes the chemical reaction in the body easier And the root cause of rapid progress is the prevalence of a catalytic role in the body of the protein - enzyme.
Q:Chemical equation if there is a catalyst and heating, which write in the equal sign above
At the same time, the catalyst is written on, and the heating symbol is written under the equal sign. Only one is written on the equal sign
