Q:Can manganese dioxide be used as a catalyst for various chemical reactions?
Catalyst in the reaction process involved in the reaction, after the completion of the reaction was reduced to the original ingredients.For example: heating decomposition of potassium permanganate when added potassium permanganate potassium potassium permanganate decomposition process, the potassium permanganate is involved in the reaction, The specific way is not clear.Finally, the occurrence of potassium permanganate before and after the reaction of the catalyst changes in morphology, particles into powder, powder particles and so on.
Q:What is chemical adsorption and its relationship with heterogeneous catalysis
The catalytic cycle includes five steps: diffusion, chemical adsorption, surface reaction, desorption and reverse diffusion.The chemical adsorption is an important part of the heterogeneous catalysis process, and the adsorption of the reactants on the catalyst surface,
Q:What is the nature of the catalyst before and after the chemical reaction?
Only catalyze, do not participate in the reaction! The
Q:Chemical production of iodine and magnesium with water as catalyst!
In the 250mL three bottles were equipped with spherical condenser and constant pressure dropping funnel, in the condensate tube connected to the anhydrous calcium chloride drying tube. The flask was placed with 1.5 g of magnesium chip and a small tablet of iodine, 10 g of bromobenzene and 30 mL of anhydrous ether were mixed in a constant pressure dropping funnel. First 1/4 of the mixture into the flask, a few minutes later see the magnesium surface of the bubble generated, the solution was slightly cloudy, iodine color began to disappear. If no reaction occurs, use a hot water bath. After the start of the reaction, stir, slowly dropping the remaining bromophene ether solution, dropping the rate to keep the solution was slightly boiling state, after adding, in the water bath to continue reflow 0.5h, magnesium tablets full effect.
Q:Why are transition metals more likely to be catalysts?
there are so much catalysts made up of transition metals. because one of the characteristics of transition metals is can be made to catalyst. one of the catalyst that is mostly used is iron fillings which is used as catalyst to make ammonia from nitrogen gas and hydrogen gas.
Q:What is a catalyst/catalase? help?
A catalyst is a chemical which speeds up a reaction but without being used up in the reaction, so can be used over again. Catalase is an example of an enzyme which are biological catalysts ie speed up reactions in cells. Enzymes are specific and the enzyme catalase breaks down hydrogen peroxide to water and oxygen. A catalyst which also breaks down hydrogen peroxide is manganese dioxide.
Q:Explanation of Catalysts?
A catalyst provides an alternative reaction pathway with a lower activation energy. So it speeds up the rate of reaciton because the energy of the particles/reactants doesnt have to be that high to OVERCOME the activation energy so it can therefore react. The activation energy is the minimum amount of energy required for particles to react, so the lower it is, the more faster a rate of reaction will be.
Q:what is the difference between enzyme and catalyst?
Enzymes and catalysts both affect the rate of a reaction. The difference between catalysts and enzymes is that while catalysts are inorganic compounds, enzymes are largely organic in nature and are bio-catalysts. Even though all known enzymes are catalysts, all catalysts are not enzymes. Moreover, catalysts and enzymes are not consumed in the reactions they catalyze. Catalysts are low molecular weight componds, enzymes are high molecular globular proteins. Catalysts are inorganic, enzymes are organic. Catalyst reaction rates are slower (usually) than enzyme reaction rates. Catalysts are not generally specific - enzymes are VERY specific. Catalysts increase or decrease the rate of a chemical reaction, enzymes are proteins that incrase the rate of chemical reactions & convert the substrate into product. There are 2 types of catalysts - (positive & negative), and the 2 types of enzymes are activation enzymes and inhibitory enzymes. Catalysts are simple inorganic molecules, while enzymes are complex proteins.
Q:Chemical equation if there is a catalyst and heating, which write in the equal sign above
At the same time, the catalyst is written on, and the heating symbol is written under the equal sign. Only one is written on the equal sign
Q:how do catalysts help in green chemistry?
Catalysts reduce the energy barrier for reactions, meaning they require less energy to make the forward reaction go. This means less heat, light, or other energy sources are required to perform the same reaction without a catalyst. Also, by definition, a catalyst is not consumed in a reaction and can therefore be recycled many many times before replacement is necessary.
