FAQ

Chemical reaction plus catalyst on the △ H no effect
The catalyst only affects the reaction rate of the substance and increases its activation energy, and the enthalpy change is only related to the initial state of the substance, independent of the reaction process.
What is the catalyst condition in the chemical equation?
On the middle of the equal sign or arrow above ah ~
Pls help me define a catalyst.?
A substance which speeds up or slows down a reaction without taking part in it.
How are the 4 characteristics of a catalyst (1. organic or inorganic 2. reusable 3. Highly specific, and 4. lowers activation energy) important in preforming life functions? please be as specific as possible, i understand that these are characteristic, i just don't understand why they're beneficial, other than the reusable and lowers activation energy one.
Organic or Inorganic - the catalyst (enzyme) must be organic to be found in the cell. Catalysts speed up chemical reactions inside a cell and must therefore be organic to be a functioning part of the cell. Reusable - There are so many reactions that catalysts are involved in that it would be a waste for the cell if a catalyst could only last one reaction, especially if there are inhibitors and competition for the active site. Catalysts must be reusable in order to keep the cell functioning. Catalysts always remain unchanged after a reaction. HIihly Specific - Catalysts are only made to catalyze one specific chemical reaction. Their active site has proteins bonded in such a way that only certain elements can enter the active site and H bond with those proteins. The fact that they are highly specific maximizes the productiveness of the cell. And it ensures that the cell only has catalysts to reactions that it needs to be completed. It also ensures that the elements are correctly bonded with eachother. If any two elements could enter the active site, there is no guarantee that the correct product will be produced. Catalysts and Enzymes must be super highly specific in order to properly function. Lowers Activation Energy - The more energy a cell has to spend to catalye a reaction, the worse it is for the cell and the less ATP is has for other reactions. Catalyts hold the substrates together so there is less energy that is needed to have the two substrates react with eachother. Activation Energy is the energy that is needed to start a reaction. So the less energy used by the cell for reactions, the better for the cell. Hope this helps
The future direction of employment how, in what kind of units to do what work, how the closure rate? The
Generally in the chemical plant to do engineering design engineers, the past few years, science and engineering graduates generally do not worry about work.
The chemical reaction equation of methanol heating and oxygen in the presence of catalyst
2CH3OH + O2 === 2HCHO + 2H2O
woulld you be able to answer these aswell i really dont know how to do this cehmestryExplain how, and why, an atom of chlorine (Cl) and an atom of lithium (Li) would form a chemical bond with each other. (iii)Explain what is meant by electronegativity and how it can be used to determine the nature of a chemical bond. (iv)Write a note outlining what is meant by vapor pressure and explain how the concept is used to define the boiling point of a liquid.
Because of the production of photochemical oxidants from NOx reacting with hydrocarbons in sunlight Noxer blocks are used to rid the NOx from the surroundings through The titanium dioxide (TiO2) on the bocks absorbs ultra-pink radiation from daylight which excites its electrons to a bigger orbital. On the outside of the crystals of TiO2 a reaction happens between oxygen and a high power electron from the TiO2. O2 + e? --O2 ? The excessive vigor electron is then given back to the TiO2 when water then reacts with the oxygen to present H2 O + O2 --H+ + O2 ? + OH Nitrogen dioxide is oxidised to nitrate ions as a result of the hydroxyl radical being an awfully strong oxidising agent NO2 + OH --H+ + NO3 ? The superoxide from response 3 also varieties nitrate ions from nitrogen monoxide. NO + O2 ? --NO3 ? This nitrate is washed away through rain or combines with the concrete within the block.
What is the relationship between the catalyst and the chemical reaction? What is the relationship between the enzyme and the catalyst?
Catalytic, also known as catalyst, is defined in the junior high school stage to be able to change the rate of chemical reactions, and its own quality, composition and chemical properties remain constant before and after chemical reactions. For example, manganese dioxide can be used as hydrogen peroxide (hydrogen peroxide) decomposition of the catalyst. The catalyst is divided into the positive catalyst and the catalyst is used. The positive catalyst contributes to the reaction to move in the positive direction, and the reverse catalyst contributes to the reaction to move in the reverse direction.
