Q:What is the quality of the catalyst in the chemical reaction,and how much is the catalyst mass?
You can not calculate this question, the quality of the catalyst before and after the same reaction, how much reaction before the reaction on how much
Q:the heterogenous catalyst ZSM-5 IS used to convert ?
Zeolite-based heterogeneous catalysts are used by industrial chemical companies in the interconversion of hydrocarbons and the alkylation of aromatic compounds. A very good example is the zeolite ZSM-5. This zeolite, developed by Mobil Oil, is an aluminosilicate zeolite with a high silica and low alumininum content. Its structure is based on channels with insecting tunnels. The aluminium sites are very acidic. The substitution of Al3+in place of the tetrahedral Si4+ silca requires the presence of an added postive charge. When this is H+, the acidity of the zeolite is very high. The reaction and catalysis chemistry of the ZSM-5 is due to this acidity. The ZSM-5 zeolite catalyst is used in the petroleum industry for hydrocarbon interconversion. An example use is in the isomerizations of xylene- from meta to para-xylene. The acidic zeolite promotes carbocation isomerizations. There are two suggested mechanisms for this type of isomerizations. Firstly shape may play a role. Perhaps para-xylene has a shape which allows it to diffuse rapidly through the zeolite structure, whereas as meta-xylene takes longer to pass through the zeolite and thus has more opportunity to be converted into the para-xylene. Secondly, is that the orientation of reactive intermediates within the zeolite channels favors specifically para-xylene.
Q:Does the catalyst affect the chemical reaction rate constant?
The positive catalyst will increase the constant, negat
Q:High chemistry: Does the catalyst affect the heat and heat of the reaction?
No effect
Q:What is the catalyst for industrial aluminum electrolysis?
2AlCl3 (melt) = power = 3cl2 + 2al by-product is chlorine
Q:How does the catalyst affect chemical balance?
The catalyst only affects the time required to reach equilibrium and does not affect the conversion of the reactants
Q:The role and significance of chemical catalysts
To speed up or slow down the chemical reaction is to make the chemical reaction more direct, simple and straightforward to adopt
Q:High school stage which organic chemical reactions do not use catalyst
Olefins, alkynes, making bromine water, potassium permanganate fade.
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:describe a biological catalyst?
A biological catalyst is a subclass protein called an enzyme. Enzymes are biological catalysts that increase the rate of chemical reactions. A catalyst does the following: 1) Increases the rate of reaction 2) Is not itself changed at the end of the reaction 3) Does not change the reaction or its final result The amount of energy required for this reaction is called activation energy. The enzyme lowers the activation energy necessary for the reaction to take place, thus speeding up the process.
