Q:What is the reaction in chemistry?
Industrial production of ammonia, ethanol, industrial synthesis of ammonia, ethanol catalytic oxidation, acetaldehyde oxidation into acetic acid, ethyl acetate preparation, the transformation of automobile exhaust, benzene substitution reaction and addition reaction, some other addition reaction of hydrocarbons, Ethanol dehydration to produce ethylene and so on
Q:Describe the role of a catalyst..........?
Describe Catalysts
Q:Why are enzymes classified as organic catalysts?
Enzymes Are Classified As
Q:Compare and contrast enzymes and catalysts?
Enzymes are actually biological catalysts composed of hundred of amino-acids, which are produced by living organisms. They are responsible for a number of reactions and biological activities in plants, animals, human beings and micro-organisms. There are also chemical catalysts that interact with other reactants and modify them without being changed themselves.
Q:How does the catalyst generally add to the organic chemical reaction?
In the case of heterogeneous catalysis, the specific surface of the catalyst, in addition to the activity of the catalyst, is an important factor in determining the reaction rate, which means that the specific surface for catalysis is large and the reaction is as fast as the whole. So the overall principle in understanding the activity of the premise of the catalyst, would like to quickly add a little more.
Q:What is the maximum impact of the chemical reaction rate?
The catalyst certainly affects the most
Q:Chemical equation if there is a catalyst and heating, which write in the equal sign above
This do not care The But in general the catalyst is written on the equal sign is better ...
Q:catalyst question?
It makes a reaction run faster and better AND it is not used up by the 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.
Q:Nitrogen and hydrogen in the role of high temperature and pressure catalyst to generate ammonia chemical equation
N2 + 3H2 = catalyst, high temperature and high pressure = 2NH3
