Q:What makes an enzyme a catalyst?
A.hydrogen peroxide. Catalase is an enzyme that functions in the decomposition of hydrogen peroxide to oxygen and water.
Q:All high school chemistry uses sulfuric acid as a catalyst for the reaction
Esterification reaction (dehydration), nitration (dehydration, concentrated nitric acid), carbonation reaction or dehydration reaction (organic matter in sulfuric acid blackening, dehydrating agent), sulfonation reaction (dehydrating agent), ethylene (dehydrating agent).
Q:What does what does catalyst mean?
a catalyst enables a reaction to occur quicker, by lowering the activation energy, and finding it an alternate path way to react. example of a catalyst is an enzyme, found in our saliva, it helps us digest our foods, by breaking it down into smaller pieces.
Q:NH3 and O2 in the presence of catalyst in the chemical reaction occurred how to write,
4NH3 + 5O2 == 4NO + 6H2O
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:Does the nature and quality of the catalyst itself change before and after the chemical reaction?
Will not change! In fact, the catalyst in the chemical reaction is to participate in the reaction, but in the reaction it not only participate in the reaction, but also generated, and the amount of reaction and the amount of equal, the total amount of the same, this process is more complex, But sometimes the problem will appear, but the information will be very clear, will not affect the problem!
Q:Does all chemical reactions have a catalyst?
Not some reaction without catalyst
Q:When there is a catalyst in the chemical equation, it is not necessary to match the atoms of the catalyst
The habit of writing is not to write the catalyst involved in the equation, it is usually written in the equation above the equal or below
Q:what function does catalyst have?
The answer above mine is correct. You should also note that a catalyst does not take part in the reaction: it just makes things easier as the previous person said.
Q:What is a catalyst?
The catalyst itself reduces the energy barrier (Ea, activation energy) of the chemical reaction, making the reaction easier.
