Q:What are catalysts and enzymes?
A catalyst is a substance which is used to increase or decrease the rate of a reaction, without itself undergoing any chemical change. There are two types of catalysts, positive and negative. Positive catalysts are used to increase the rate of a reaction while negative catalysts are used to decreasing the rate of a reaction. Enzymes are proteins which act as catalysts in biochemical reactions. They operate between a certain pH level and temperature. If there is a change in pH level or temperature, their efficiency decreases.
Q:Chemical "catalyst can speed up the chemical reaction rate of other substances," this sentence right?
Wrong, the catalyst is divided into two kinds, one is to speed up the chemical reaction speed, and the other is the opposite
Q:What reactions need catalysts?
Reactions that have high Activation Energy need catalysts to speed up reactions. These reactions aren't spontaneous since the reactants do not have enough energy to overcome the activation energy barrier. Catalysts are compounds that speed up reactions by providing an alternative pathway for the reaction. It is a common misconception that catalysts lower the activation energy. It doesn't actually lower the activation energy, instead it provides an alternative pathway with lower activation energy. For example, breakdown of hydrogen peroxide happens in nature but, relatively slowly. When you add a little bit of manganese dioxide, the breakdown happens a lot faster. Another example is, breakdown of glucose in the body. It is facilitated by an enzyme called amylase (or carbohydrase). An industrial example is the use of vanadium pentoxide (V2O5) in the Contact process, where SO2 is converted to SO3 in the presence of V2O5. Hope that helps!
Q:When there is a catalyst in the chemical equation, it is not necessary to match the atoms of the catalyst
No, the catalyst is written above the equal sign, not the reactants, nor the product
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:How does active charcoal catalyze in some chemical reactions?
Generally not, but it can be used as a catalyst carrier
Q:What is the catalyst in the end?
You said the chemical catalyst or Ati graphics card catalyst? If the above is enough to explain the above, if it is the latter, that is, the meaning of the graphics card, Ati's graphics drive like a catalyst
Q:The beginning of the chemistry plus the catalyst and the plot without the Cuihua agent
Plus the rate of fast
Q:Is the catalyst in the field of inorganic chemistry?
In particular, the chemical and homogeneous catalysis of inorganic chemistry has deep origins. Inorganic chemistry, oxides (such as metal oxides), family elements (such as the chemical behavior of transition metal elements) can be provided for catalytic science Support and guidance.
Q:Is palladium predominantly a catalyst in chemistry?
Palladium in the chemical mainly to do the catalyst; palladium and ruthenium, iridium, silver, gold, copper and other alloy, can improve the palladium resistivity, hardness and strength, used in the manufacture of precision resistors, jewelry and so on.
