Q:what is a catalysts and how can they be useful?
A catalyst is a substance that speeds up the rate of a chemical reaction with itself being chemically unchanged at the end of the reaction. They are useful as they help to lower the minimum amount of energy needed ( also known as activation energy) to start the reaction. Hence, by lowering the activation energy of the reaction, they help to speed up the rate of reaction. For example, in the Haber process for the manufacture of ammonia, the catalyst iron is added to speed up the rate of reaction between hydrogen gas and nitrogen gas. Otherwise, the reaction would have proceeded much more slowly. Another example is the catalyst nickel used in the manufacture of margarine and vanadium (V) oxide for manufacturing sulfuric acid. As catalyst remain chemically unchanged after a reaction, they can be reused again and hence, they are required in minute amounts. An example is the washing powder used in washing clothes, they help to remove food stains by digesting the proteins in food. They can be reused after each reaction and hence, you do not need to add in the whole packet of washing powder but only a few spoonful.
Q:How the catalyst accelerates the chemical reaction
Reduced the activation energy required to reflect
Q:What are the requirements for the catalyst for the chemical industry?
Generally find a few, according to the cost and cost of cost, choose cost-effective
Q:The properties of scandium
Sci-Scandium (Sc) Basic knowledge Introduction In 1879, Swedish chemistry professor Nelson (LFNilson, 1840 ~ 1899) and Clive (PTCleve, 1840 ~ 1905) were almost simultaneously in rare mineral silica beryllium yttrium and black The mine found a new element. They named this element "Scandium" (scandium), ...
Q:Briefly define a homogenous catalyst? Help please!?
Define Homogenous
Q:What is the catalyst condition in the chemical equation?
Do you want to play on your computer? Trouble ah ~ no you add brackets it ~ word may be able to try ~ I have not studied ~ now look ~
Q:What are the examples of chemical catalysts used in life?
Clothing. "New synthetic fiber made of clothing, soft and comfortable and cheap and durable. Cloth from natural fibers to man-made fibers, and then to the development of synthetic fibers, dyes from the original natural dyes to the current synthetic dyes, reactive dyes , All reflect the contribution of chemistry to the development of clothing, chemical clothing from the initial cover utility, into today's beautiful, convenient, with a special function of the utility, it greatly enriched the style of clothing, material, use
Q:Who knows hydrogen and nitrogen in the high temperature of ammonia chemical equation ah?
3H2 + N2 ===== 2NH3
Q:Why are enzymes classified as organic catalysts?
a catalyst is something that makes a reaction go faster than it normally would. An enzyme is a catalyst; it has all the parts for the reaction on it and help organic materials break down or transfer energy or whatever reaction it needs.
Q:What about the chemical reaction of the catalyst if there is no catalyst?
The phenomenon of accelerating or slowing the rate of chemical reactions due to the intervention of the catalyst is called catalysis. In the catalytic reaction, the catalyst reacts with the reactants to change the reaction pathway, thereby reducing the activation energy of the reaction, which is the reason why the catalyst can improve the reaction rate.
