Q:What progress has chemistry brought to our life?
Q:What does what does catalyst mean?
the compound that allows for a chemical reaction. and example would be The enzyme catalase is the catalyst that allows hydrogen peroxide to break down into water
Q:What is the principle of the catalyst?
Because the catalyst does not participate in the reaction, it can change the rate of chemical reactions without any change in itself.
Q:Why are acids and bases good catalysts?
A catalyst is a substance that speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy. Catalysts appear not to take part in the reaction. Frequently, catalysts are not very reactive. Acids and bases, on the other hand, are very reactive. Acids (as H+) and bases ( as OH-) sometimes function as catalysts in some organic reactions. They appear to be catalysts because in the course of the mechanism H+ or OH- is regenerated.
Q:Is it possible for the different chemical reactions to have the same catalyst?
Just as manganese dioxide can catalyze the decomposition of molten potassium chlorate can catalyze the decomposition of hydrogen peroxide, but this is not necessarily the same as the catalyst for the production of the same product, but for the enzyme in order to ensure that the growth of the orderly all have a single Enzymes can only catalyze an organic matter
Q:Briefly define a homogenous catalyst? Help please!?
Define Homogenous
Q:What is the PTC catalyst in chemistry?
1, polyether chain polyethylene glycol: H (OCH2CH2) nOH chain polyethylene glycol dialkyl ether: R (OCH2CH2) nOR2, cyclic crown ethers: 18 crown 6,15 crown 5, Fine and so on. 3, quaternary ammonium salt: commonly used quaternary ammonium salt phase transfer catalyst is benzyl triethyl ammonium chloride (TEBA), tetrabutyl ammonium bromide, tetrabutylammonium chloride, tetrabutylammonium hydrogen sulfate (TBAB) , Trioctylmethylammonium chloride, dodecyltrimethylammonium chloride, tetradecyltrimethylammonium chloride, and the like. 4, tertiary amine: R4N X, pyridine, tributylamine and the like. 5, quaternary ammonium base (its alkaline and sodium hydroxide similar) soluble in water, strong hygroscopicity. 6, quaternary phosphonium
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:Catalyst - Can it decrease the rate of a reaction?
A catalyst is something that quickens the fee of reaction without getting used up itself. They many times try this by skill of lowering the activation skill, which additionally brings the optimal temperature down. So, to place it only, it relatively is B.
Q:NH3 and O2 in the presence of catalyst in the chemical reaction occurred how to write,
4NH3 + 5O2 == 4NO + 6H2O
