Q:Before and after the reaction, the chemical properties and quality of the water did not change, and the water was the catalyst
Dry aluminum powder and iodine does not react, there is water to react.
Q:The concept of catalyst in high school chemistry
The catalyst is selective, that is, a catalyst that catalyzes only one or more chemical reactions and does not catalyze all chemical reactions. However, a chemical reaction of the catalyst may be a variety of, such as hydrogen peroxide to produce oxygen in the reaction, in addition to the use of manganese dioxide as a catalyst, you can also use copper oxide, iron oxide as a catalyst. Building on the use of cement, red brick powder also catalyze the decomposition of hydrogen peroxide.
Q:why are enzymes called catalysts?
Enzymes okorder.com/...
Q:How are a catalyst and an intermediate similar? How are they different?
A catalyst speeds up the rate of a reaction by lowering the activation energy barrier which is, presumably, the energy required to achieve the reaction intermediate. Catalysts are also not consumed in the reaction, they are regenerated towards the end. A reaction intermediate is a configuration that a molecule takes prior to achieving it's lowest energy form which would signify the end of the reaction. Intermediate usually are hard to isolate because of the incentive to go to the most stable configuration. How are they different? A catalyst is not a part of the reaction product and it doesn't get consumed. An intermediate in a reaction is transformed into the product. How are they similar? Well, catalysts drive the reaction and make it easier for the reaction for follow through. Since intermediates are high energy and thermodynamics tells us that low energy is favorable, the incentive for a high energy intermediate to drive down to it's stable for can also drive a reaction. I hope that helps. I hope it makes sense.
Q:Comparison of biocatalysts with chemical catalysts!
biocatalyst activity is adjustable, can be subject to hormones and other active regulation of hormones.
Q:Catalyst and Intermediate.?
Cl is the catalyst. ClO the intermediate. The catalyst is the component which does not change in overall reaction. He forms some intermediate component(s) with the reactants. In the later reaction steps the intermediate(s) react forming the catalyst in its original state. (a) The overall order is the sum of the orders with respect to the components: n = 1 +1 = 2 (b) the unit of the rate of reaction is r [=] mol/ (Ls) (more general mol per unit time and volume) compare dimensions mol / (Ls) [=] k · mo/L · mol/L =k [=] L/(s mol) (more general unit volume per unit time and mole) (c) First reaction For elementary reaction steps the order of the reaction rate with respect to a reactant is equal to stoichiometric coefficient. Hence the rate of first reaction is: r₁ = k₁·[Cl]·[O₃] Overall rate is given by the rate determining step, while other reaction steps are in equilibrium: r = r₁ = k₁·[Cl]·[O₃] If second reaction is the rate determine step r₂ = k₂·[O]·[ClO] while reaction 1 is at equilibrium K₁ = ( [ClO]·[O₂] ) / ( [Cl]·[O₃] ) =[ClO] = K₁·( [Cl]·[O₃] ) / [O₂] the overall rate would be: r = r₂ = k₂·[O]·[ClO] = K₁·k₂·[O]·[Cl]·[O₃] / [O₂] = k·[O]·[Cl]·[O₃] / [O₂] That doesn't match the observed rate law
Q:Does a catalyst have an effect on the Gibbs free energy of a reaction?
A catalyst can change the activation energy not the Gibbs energy. The Gibbs energy is the energy difference between the initial state and final state. A catalyst cannot change that. Imagine you are driving from school to home. How you drive do not change the height difference between the school and your home. However, a catalyst can change your path which can change the routine you drive from school to home. So if there is a hill in between your school and you home, you have the choice to drive through it or drive around. Here is a picture: upload.wikimedia.org/wikipedia/co... A catalyst can change the height of the barrier, but cannot alter the initial or final state.
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: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:describe a biological catalyst?
A biological catalyst is a subclass protein called an enzyme. Enzymes are biological catalysts that increase the rate of chemical reactions. A catalyst does the following: 1) Increases the rate of reaction 2) Is not itself changed at the end of the reaction 3) Does not change the reaction or its final result The amount of energy required for this reaction is called activation energy. The enzyme lowers the activation energy necessary for the reaction to take place, thus speeding up the process.
