- Q:What is catalyst in Science?
- A catalyst is a substance that increases the rate of a reaction by decreasing the activation energy (energy required to start the reaction). It does so by creating a new reaction mechanism (the way the reaction happens on a molecular level) that happens more easily and with less energy. For example, a catalyst could attract both reactants, thus bringing them directly together and facilitating the reaction.
- 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:Why does the CuO catalyze the reaction rate faster and faster when catalyzing the decomposition of hydrogen peroxide or tell me how to make the catalyst catalyst faster
- CuO exothermates when catalyzing the decomposition of hydrogen peroxide, so the reaction becomes faster.
- Q:pls give one or two catalysts that are used in the industry for example:Rhodium catalyst in a catalytic converter of a car or the Iron catalyst for making ammoniaTHANKS :)
- u . s . a . of america has an excellent style of organic gas. In theory that's accessible to have an electric powered motor force a compressor to take the low stress gas to make it dense adequate to get adequate interior the vehicle to run for a mutually as (in actuality, gas stations with organic gas pumps do it precisely like that, that's no longer trucked to them, we've a pair in Dallas) the real undertaking is that, specific it will be pressurized, requiring a greater perfect tank than propane, that's a liquid interior the tank, and the tank must be a cumbersome cylinder for capability or numerous smaller cylinders area by making use of area. Getting this into the physique of the vehicle devoid of doing away with all the storage/bags area isn't ordinary. And ultimate efforts nevertheless finally end up with the miles in line with fill up being decrease than the gas which inserts in a small area.
- Q:Exemplify the use of green catalysts in green chemistry
- How can a green catalyst, they do not react
- Q:Could you tell me all the differences between those two catalysts? Thank you very much.
- Biochemical Catalyst
- Q:What is the definition and function of the catalyst in chemistry?
- Definition: in the chemical reaction can change the chemical reaction rate of other substances, and its own quality and chemical properties before and after the reaction did not change the material called catalyst, also known as catalyst. The role of the catalyst in the chemical reaction is called catalysis. The use of a catalyst only changes the rate of chemical reaction and does not alter the quality of the product.
- Q:Thorough explanation pls.
- by lowering the activation energy
- Q:What is the principle of catalyst reaction rate in chemical reactions?
- Can significantly change the reaction rate and its own chemical properties and quantity in the reaction before and after the basic material unchanged. The catalyst has a positive catalyst (i.e., accelerates the reaction rate) and a negative catalyst (i.e., reduces the reaction rate), and generally does not specifically refer to both the positive catalyst.
- Q:What about the chemical reaction of the catalyst if there is no catalyst?
- The phenomenon of accelerating or slowing the rate of chemical reactions due to the intervention of the catalyst is called catalysis. In the catalytic reaction, the catalyst reacts with the reactants to change the reaction pathway, thereby reducing the activation energy of the reaction, which is the reason why the catalyst can improve the reaction rate.
