How would a catalyst change the reaction energy diagram?
The overall enthalpy change in a common reaction would not change. Only the path to get there would change. A catalyst basically lessens the activation energy required to get the reaction to take place.
What is the function of anhydrous zinc chloride in the formation of fluorescein?
Zinc Chloride catalyses the reaction of e.g. phatalic anhydride and resorcinol. If you head these three as powdered substances with a bunsenburner, they react much faster. After solving this mixture in water, you can filtrate the Zinc Cholride out of the solution. For more examples what a catalyst does, read Wiki or Google catalyst. Good Luck
What is the significance of the zero order rate law in chemical kinetics and how does it impact the rate of a reaction?
The zero order rate law in chemical kinetics is significant because it shows that the rate of a reaction is independent of the concentration of reactants. This means that the rate of the reaction remains constant regardless of how much reactant is present. This can be useful in determining the overall reaction rate and understanding the reaction mechanism.
How a catalyst increases the rate of a reaction?
There are two ways in which catalysts work. You already know that when two different molecules bump into each other, they might react to make new chemicals. We usually talk about "collisions" between molecules, it would be much simpler to say that the molecules bumped into each other. How fast a chemical reaction is depends upon how frequently the molecules collide. You have probably been told about the "kinetic theory" which is all about heat and how fast molecules move around. What catalysts are doing when they make a chemical reaction go faster is to increase the chance of molecules colliding. The first method is by "adsorption", the second method is by the formation of intermediate compounds.Adsorption This occurs when a molecule sticks onto the surface of a catalyst. Make sure that you spell this word correctly; it is not the same as absorption. Here is an example: it is possible to use Platinum as a catalyst to make sulphur Trioxide from Sulphur Dioxide and Oxygen. Sulphur Trioxide is very important because it is used to make Sulphuric acid which is needed for car batteries. The molecules of the two gases (Sulphur Dioxide and Oxygen) get adsorbed (stuck onto) the surface of a Platinum catalyst. Because the two molecules are held so close together, it is more likely that they will collide and therefore react with each other. The Sulphur Trioxide easily falls off the catalyst leaving space for more Sulphur Trioxide and Oxygen.Intermediate Compounds Many catalysts, including all enzymes" work by forming intermediate compounds. What happens is very simple: the chemicals involved in the reaction combine with the catalyst making an intermediate compound, but this new compound is very unstable. When the intermediate compound breaks down it releases the new compounds and the original catalyst.
What is meant by the rate of reaction?
The how much speed it takes for two substances to make one product. Many factors can affect this including the temperature, the surface area, the concentration, the catalyst and the pressure (only applies for gases)
What is different between catalyst and hardener?
The term catalyst is much more general than the term hardener, since hardening is only one of endless numbers of processes which can be catalysed. A hardener, therefore, would be a specific type of catalyst.
If you used 10mL of an inorganic catalysts in a reaction how much would be left over after the reaction was done?
The amount of catalyst left over after a reaction depends on various factors such as its reactivity, consumption in the reaction, and conditions. Without additional information, it is not possible to determine how much catalyst would be left over after using 10mL in a reaction.
How does catalyst affect the activation energy of chemical reaction?
The presence of a catalyst affects the activation energy of a reaction by lowering the activation energy, helping the reaction go faster and making it so the reaction does not have to use as much energy to fulfill the products.
Why use reactant in the powdered form?
A lump of solid has a much lower surface area compared to a powdered catalyst. Since most chemical reactions that are catalysed by solid phase catalysts (heterogeneous catalysts) occur on the catalyst surface more surface area = faster reaction.
How would a catalyst change the reaction energy diagram?
The overall enthalpy change in a common reaction would not change. Only the path to get there would change. A catalyst basically lessens the activation energy required to get the reaction to take place.

What is the catalyst used in haber?
its an iron catalyst (iron oxide)
How a catalyst effects chemical reaction?
Catalysts allow chemical changes to occur much more rapidly. Reactions that usually take years can happen before your eyes in seconds. From my understanding there is no 100% agreed upon reason for how they do this. There are a number of widely regarded theories though.
Why does a catalyst cause a reaction to proceed faster?
It decreases the activation energy, or the energy barrier the reactants must go through to form products. This is the same thing as the energy of the transition state. By decreasing the activation energy necessary for the reaction to occur, more reactants are able to form products since not as much energy is needed. See the Web Links to the left of this answer for more information.
What fits with an enzyme to make a reaction occur?
The substrate fits into the enzyme, much the way a key fits in a lock. Sometimes there are other "modulators" that also fit in the enzyme.
Does enzyme is a protein that acts as a catalyst?
Yes, enzymes are proteins that act as biological catalysts, speeding up chemical reactions within cells by lowering the activation energy needed for the reaction to occur. This allows biochemical reactions to happen at a much faster rate than they would without enzymes.
When you Reduce activation energy what happens?
Reducing activation energy allows chemical reactions in the cells of living things to occur at temperatures at which the cells can survive. Reducing activation energy is carried out by enzyme catalysts. The enzyme catalysts are not used up in the reaction, and can be used in subsequent chemical reactions.
