Q:Thorough explanation pls.

Catalyst are the substances which increase the rate of reaction. They do not get consumed in the reaction but they participate in intermediate reactions. The catalyst action can be explained as- Providing alternate energy path- Let us suppose that an endothermic reaction need 15 joules of threshold energy to occur. The catalyst will provide them path which needs less energy. Providing Surface- Many reaction may occur slowly because less contact between the molecules/atoms/ions or due to unavailability of proper structure, in this case the catalyst provide surface for carrying the reactions. There are several other actions which mayn't be necessary for you to understand the basic function of catalyst.

Q:Describe the role of a catalyst and a substrate in a chemical reaction.

Describe Catalysts

Q:High school knowledge __ teacher do not know right!

Nothing to do, but with the percentage of activated molecules, is proportional to

Q:It is best to tell me what the role of sulfuric acid in these reactions, respectively

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:Chemical Reactions Under what circumstances the catalyst accelerates the reaction

First, more than ninety-nine percent of the catalyst is accelerating the reaction, and if the catalyst kinetics reduces the energy barrier of the reaction, the reaction will naturally accelerate.

Q:Is it faster or slower? The What if you do not?

The junior middle school textbook is defined as "no reaction" but in fact the catalyst reacts first with a reaction and then the product reacts with other reactants, which will speed up the rate of reflection. Not all catalysts can speed up the reaction rate, but the organic catalyst is more efficient than the inorganic catalyst. "Hydrogen peroxide reacts with hydrogen peroxide more quickly than hydrogen chloride reacts with hydrogen peroxide.

Q:Can a catalyst decrease the rate of a chemical reaction? Please give an example if yes.

no, by defintion the catalyst speeds up the reaction.

Q:Will the catalyst in the chemical reaction be reduced?

The amount of catalyst in the chemical reaction is not reduced, the catalyst is divided into a positive catalyst and a negative catalyst, the positive catalyst promotes the reaction, and the negative catalyst inhibits the reaction

Q:Chemical questions: "CO2 and H2 in the catalyst conditions have a reaction, the reaction of the chemical equation is"

CO2 + H2 = CO + H2O (conditions: catalyst, generally already heating, and reversible)

Q:Biological enzymes and chemical catalysts of the differences in the source, nature and catalytic characteristics of the different, specific point

Catalyst catalytic reaction relative conditions higher, selectivity than biological enzymes
