Q:What are the characteristics of the catalyst in the chemical reaction?
In simple terms: the catalyst itself is involved in the reaction, the quality of the reaction before and after the same, the ingredients do not change. The catalyst can change the rate of chemical reaction, increase the rate of reaction called catalyst, slow the inhibitor.
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:Hydrogen and nitrogen in the high temperature and pressure and catalyst conditions for the synthesi
3H2 + N2 catalyst iron ---> 2NH3 conditions high temperature and high pressure
Q:What is positive and negative catalyst in chemistry?
Positive catalyst can simultaneously speed up the positive and negative reaction rate
Q:The quality and nature of the catalyst before and after the chemical reaction did not change this sentence wrong?
This sentence is true, ah, may practice mistakes in the bar.
Q:why is palladium/platinum a good catalyst?
Palladium and platinum can form partial bonds with other molecules. By forming these partial bonds, the bond in the actual molecule gets weaker and weaker and hence, the bond becomes easier to break. Let's say for example a hydrogen molecule. There is a single bond between the 2 hydrogen atoms. Platinum/palladium will form partial bonds with the 2 hydrogen atoms. By doing so, the single bond BETWEEN THE 2 HYDROGEN ATOMS gets weaker and weaker. Hence, a smaller amount of energy is needed to break the bond between the 2 hydrogen atoms (the hydrogen molecule). As the amount of energy needed to overcome the bond between the 2 hydrogen atoms gets smaller, we say the activation energy for the reaction has been reduced. Hence, a greater amount of bonds in hydrogen molecules can be broken in a smaller time, and therefore, we say palladium/platinum has catalysed the reaction.
Q:What is the role of the catalyst in chemical knowledge?
Positive catalyst is to speed up the negative catalyst to slow down some reaction must be used to the catalyst otherwise difficult to react
Q:Several experiments were carried out using catalysts
Hydrogen peroxide in the manganese dioxide as a catalyst for decomposition reaction: 2H2O2 == MnO2 == 2H2O + O2 ↑ (laboratory oxygen principle)
Q:Is catalyst a metal or just a hard material?
A catalyst is something that enables a process to take place without being part of said process itself, such as in a chemical reaction.
Q:What are the characteristics of the catalyst in the catalytic reaction?
The role of the catalyst in the chemical reaction is to change the rate of chemical reaction, and its own quality and chemical properties do not change.
