Activation energy (Ea) is the minimum energy required for a chemical reaction to occur. It is the energy barrier that reactants must overcome to be converted into products. 2. Role of a Catalyst: A catalyst is a substance that increases the rate of a reaction without being consumed in ...
Sometimes a reaction depends on catalysts to proceed. In that case, changing the concentration of the catalyst can speed up or slow down the reaction. For example, enzymes speed up biological reactions, and their concentration affects the rate of reaction. On the other hand, if the enzyme is ...
When temperature increases, the amount of atomic or molecular collisions between molecules increases. But the change in reaction rate with temperature is not just a function of the temperature; instead, temperature increases actually affect the rate constants (written k) of reactions in a predictable ...
How withdrawal of the reaction column in the spent catalystPROBLEM TO BE SOLVED: To provide a method for extracting a catalyst in a reaction tower which can achieve the improvement of working efficiency and cost reduction, and improve the recovery yield of the catalyst.川上 勝彦...
The rate of reaction is simply how fast the reaction occurs. Some reactions, like explosions, are very fast. Other reactions, like the rusting of iron, are much slower. Several things can affect the rate of the reaction including the temperature, pressure, or presence of a catal...

The silver nitrate is a catalyst, a substance that makes a reaction go faster without participating in it. The sulfuric acid, in addition to removing the alcohol from the air, also might provide the acidic condition needed for this reaction. During this reaction, the reddish-orange dichromate ...
Blasting caps are used as a catalyst to set off the explosives loaded in support columns. Photo courtesy ImplosionWorld.com These days, blasters often use anelectrical detonatorinstead of a traditional fuse. An electrical detonator fuse, called alead line, is just a long length of electrical wir...

The need to limit antibiotic therapy due to the spreading resistance of pathogenic microorganisms to these medicinal substances stimulates research on new therapeutic agents, including the treatment and prevention of animal diseases. This is one of the g
