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:Why are there so many catalysts?
Many important chemical reactions require inputs of energy to proceed. If a catalyst is present less energy will be required to complete the reaction. Catalysts are substances that are mixed in with materials that are to be reacted, but they themselves do not, in the end, change chemically. They establish a local environment that promotes one or more chemical reactions to take place. A catalyst is important in many industrial processes. Sulfuric acid, which is used to produce batteries, detergents, dyes, explosives, plastics, and many other produces, is commonly produced using a catalyst called vanadium oxide. Ammonia, a primary component of many fertilizers, could not be produced economically without the use of iron oxide which speed up the reaction. The process of catalyst also affects the state of our global environment. Automobiles use catalytic converters to treat exhaust. The metals platinum and palladium facilitate the chemical conversion of noxious gases to more inert forms, greatly decreasing the environmental impact of combustion engines. Probably the most important impact of catalyst is on life itself. All important biochemical reactions are catalyzed by molecules called enzymes. Most enzymes are proteins which catalyze specific reactions within cells. Some examples include polymerases, which synthesize DNS and RNA, peptidases, which digest protein, and ATP synthases, which produce energy for the many different cell activities.
Q:Effect of Catalyst on Chemical Reaction Rate
The catalyst can reduce the activation energy of the chemical reaction and allow the reaction to take a shortcut
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:What chemical reactions can water do the catalyst?
Many solid and solid reactions can be converted into reactions between liquids, which speeds up the reaction rate, and perhaps the water here is the catalyst.
Q:Which of the following are true about catalysts?
1. Catalysts can help to bring the reactants together in the correct orientation False. It provides an alternative pathway (of lower activation energy) for reaction to occur. 2. The chemical formula of a catalyst is written on the left hand side (reactant) side of an equation. False. Written on the arrow that show the reatctants becoming products. 3. Catalysts can provide a surface on which the reaction occurs. True. For instance platinium in the case of hydrogenation of alkenes.
Q:A biological catalyst or a chemical reaction facilitator is know as a/an?
I was always taught that it was something best learned by putting forth a bit of effort, reading a bit and embedding the info in your brain so you will remember it always. Just me I guess.
Q:When you write a chemical equation, how do you want to add "catalyst" and "?"
This is the need for your memory, write a few times, will naturally cooked
Q:Chemistry is often said that the catalyst can change the material reaction rate
The rate is related to the concentration of matter, the velocity is physically, is the vector, has the direction
Q:how do catalysts help in green chemistry?
Catalysts allow more efficient conversion of products in irreversible reactions, or they allow for the faster attainment of equilibrium in equilibrium reactions, thereby reducing time, raw material waste and emissions. Also, because catalysts are reusable, they can be recycled.
