- Q: What are the examples of chemical catalysts used in life?
- The use of new synthetic materials makes life more comfortable. Only wood, sand and grapes are natural building materials, but they need to be combined and protected with synthetic chemicals. Cement is a chemical product, As the adhesive used in the laminate and the metal used in the nail are chemical products, the glass is made by the chemist, and the improved product, such as heat-resistant glass (trade name Pyrex glass), becomes more tough. Paint is chemist design and creation, and many modern solid materials are also the same. Plastic is synthetic, they are used in kitchen and bathroom utensils, also used in the name of the product called Formica bakelite and its related materials, beverage bottles, Cutlery and utensils. Porcelain is made by chemists and used in kitchen and bathroom sinks and other fixtures. Metal is made of chemical changes made from ores. Aluminum was once a laboratory treasure, but used An electrochemical method, which now can be easily made from alumina, at least a portion of the carpet and decorative fabric used for the use of synthetic fibers and synthetic dyes to color. Freezer and air conditioner with special chemicals as coolant ; Gas and gas stoves can be used syngas or natural gas, the combustion process is still the chemical change.Our room with gas or oil industry to produce fuel to heat, this fuel is from the natural crude oil refining and chemical We have made use of synthetic chemical products and materials made in the chemical processing industry, such as plaster or wall panels, outer panels and roof panels, as well as tiles and carpets, to heat our buildings. The stove itself and the distribution of heat The pipes are made of chemical products - metal, insulating materials and ceramics. The current enters the home through the copper wire of the outsourced insulator, both of which are products of the chemical processing industry
- Q: Carbon dioxide and hydrogen in the catalyst and heating conditions, the reaction of water and methane, the chemical equation is what
- CO2 + 4H2 = catalyst, heating = 2H2O + CH4
- Q: Cl + O3 ---> ClO + O2O + ClO ---> Cl + O2= O + O3 ----> 2O2What is the catalyst? The intermediate?How do you know which is which? If the rate law is rate=k [O3] [Cl]determine:a) the overall order.b) unit for k.c) the rate determining step, justify your answer.
- 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: r? = k?·[Cl]·[O?] Overall rate is given by the rate determining step, while other reaction steps are in equilibrium: r = r? = k?·[Cl]·[O?] If second reaction is the rate determine step r? = k?·[O]·[ClO] while reaction 1 is at equilibrium K? = ( [ClO]·[O?] ) / ( [Cl]·[O?] ) =[ClO] = K?·( [Cl]·[O?] ) / [O?] the overall rate would be: r = r? = k?·[O]·[ClO] = K?·k?·[O]·[Cl]·[O?] / [O?] = k·[O]·[Cl]·[O?] / [O?] That doesn't match the observed rate law
- Q: What is the nature of the chemical catalyst?
- Can only speed up or slow down the reaction rate, can not change the reaction balance,
- Q: i know that the catalyst is not react in an reaction,,,so that i don't why could it speed up the reaction?? Further, how does the scientist determine the catalyst for certain reaction??please give me more example....i really want to know it! i do not have any idea about this...so hope your answer will help me....thanks!
- Normal reaction requires much heat and energy but a catalyst provides a space where it can be done without either since provides space for both to bump into each other and stay till they bond..so catalyst is not involved in reaction but allowed it to occur at a much lower temp and energy.
- 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: What is the relationship between the catalyst and the chemical reaction? What is the relationship between the enzyme and the catalyst?
- Enzyme is a biocatalytic biological biomolecule, a biocatalyst that accelerates the rate of biochemical reactions without changing the direction and product of the reaction. That is, enzymes can only be used to change the speed of various biochemical reactions, but not the biochemical reaction itself. Enzyme is a kind of amino acid composed of a special biological activity of the substance, which exists in all live animals and plants, is to maintain the normal function of the body, digest food, repair tissue and other life activities of a necessary material.
- Q: I know that a species that does not appear in the chemical equation may also affect the rate of a reaction - e.g. a catalyst. But does that mean the catalyst can be present in the rate equation, and if so are catalysts always present in the rate equation?
- Any reaction with a finite amount of reactants has a half-life, whether it's first order, second order, zero order or complex order. The half-life (t?) is defined as the time taken for the reaction to go half-way to completion. If the reaction is: A + B ---products and A is in excess, then t? will be the time taken for half of B to be used up. For all reactions, then, you get a decay curve. For zero-order reactions, this 'curve' is a straight line, but for all other orders, the curve is an actual curve and it is quite difficult to distinguish, by visual inspection alone, whether it is exponential (indicating a first-order reaction) or hyperbolic (indicating a second or higher order reaction).
- Q: how can you tell when a substance serves as a catalyst?
- It makes a reaction run faster and better AND it is not used up by the reaction
- Q: In the chemical reaction will have to use the catalyst reaction, such as H2O2 === (MnO2) H2O + O2 ↑, then the catalyst in the end to participate in the reaction (that is, the catalyst itself is the reactant) If so, why are some of these substances in the reaction (these substances refer to the catalyst) in the reaction after the quality and nature of the change does not change?
- In the chemical reaction can change the chemical reaction rate of other substances (both can also improve), and its own quality and chemical properties in the chemical reaction before and after the material did not change called catalyst (also known as catalyst)
