- Q: Is it faster or slower? The What if you do not?
- The junior middle school textbook is defined as "no reaction" but in fact the catalyst reacts first with a reaction and then the product reacts with other reactants, which will speed up the rate of reflection. Not all catalysts can speed up the reaction rate, but the organic catalyst is more efficient than the inorganic catalyst. "Hydrogen peroxide reacts with hydrogen peroxide more quickly than hydrogen chloride reacts with hydrogen peroxide.
- Q: What is the effect of the catalyst in chemistry?
- Changing the rate of reaction can speed up the reaction and slow down the rate of reaction
- Q: Seems intuitive that it wouldn't, but I dunno the qualitative difference between activation energy & Gibbs free energy. I'M TOO LAZY TO GOOGLE I GOTS STUFF TO DO
- 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: Explain how a catalyst may increase the rate of chemical reaction?
- A catalyst lowers the acitvation energy of a reaction.
- Q: What is the catalytic efficiency of ordinary chemical catalysts?
- Different reactions, with the same catalyst, the catalytic efficiency is different. The same reaction, with different catalysts, the catalytic efficiency is also different
- Q: The quality and nature of the catalyst before and after the chemical reaction did not change this sentence wrong? Why did the "middle school student study" say it was wrong?
- There is no wrong catalyst just to speed up the reaction
- Q: It's a GCSE Chemistry questionI just need to know why there are so many
- 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: Thorough explanation pls.
- A catalyst is a substance that increases the rate of a chemical reaction.
- Q: What is the catalyst for industrial aluminum electrolysis?
- 2AlCl3 (melt) = power = 3cl2 + 2al by-product is chlorine
- Q: how do catalysts help in green chemistry?
- Catalysts reduce the energy barrier for reactions, meaning they require less energy to make the forward reaction go. This means less heat, light, or other energy sources are required to perform the same reaction without a catalyst. Also, by definition, a catalyst is not consumed in a reaction and can therefore be recycled many many times before replacement is necessary.
