- Q: What is a catalyst and how does it make a reaction go faster?
- Wohoo i stil remember this from last year! A catalyst is a substance that speeds up the chemical reaction without being used up in the reaction itself e.g. manganese dioxide in the making of oxygen. And.. A catalyst works by providing a convenient surface for the reaction to occur. The reacting particles gather on the catalyst surface and 1) collide more frequently with each other 2) more of the collisions result in a reaction between particles because the catalyst can lower the activation energy for the reaction. A catalyst is often used as a powder, so that it has a bigger surface area per gram. Okay i copied the last bit from my science book but i remembered the first bit!! HA!
- Q: What is positive and negative catalyst in chemistry?
- Positive catalyst can speed up the reaction rate, negative catalyst can slow down the reaction rate
- Q: In the chemical reaction, why can the catalyst speed up the reaction rate
- Manganese dioxide, copper sulfate, catalytic hydrogen peroxide decomposition.
- Q: Why is the catalyst in the chemical balance, the rate of change and balance?
- Plus the catalyst, but only to change the activation energy of the reaction, so that more molecules at the same time to participate in the reaction.
- Q: I opened catalyst control center to see what its was, i didn't change anything and now when i full screen a youtube and hulu the screen will be black and the loading bar at the bottom will be stuck. I also noticed that now when i play minecraft all the blocks have a black out line i cant get rid of. I tried deleting my .minecraft and that didn't fix it.
- Catalyst control center? You, my friend, have a Radeon graphics card. What's happening is that somewhere you have Anti-Aliasing turned on. Go back into your catalyst control center and anywhere where there is an option to 'use application settings'- select it. It's supposed to improve your graphics quality, but there are a lot of bugs with it on a whole bunch of applications and games- including Minecraft. Oh, and as for the youtube thing- alt+tab should show you where your video has disappeared to. Yes, I know- it's bloody weird, but flash is buggy as heck, and Radeon graphics cards are weird; I should know- I have one too! That should do the trick! If it doesn't work then there's likely an extra option somewhere that you haven't ticked to 'use application settings'.
- Q: and what type of macromolecule are they made of? thanks!
- A catalyst is any substance that speeds up a chemical reaction without otherwise changing the outcome of the reaction. Catalysts do this by lowering a reaction's activation energy (which is the energy barrier that must be overcome before the reaction can proceed spontaneously). Catalysts are not permanently changed by the reactions they catalyze, so one catalyst could reasonably catalyze the same reaction many times over. Enzymes are biological catalysts because they lower the activation energy of metabolic reactions (and therefore increase their rate). Every enzyme has an active site that is specific for a particular substrate, or for a small related group of substrates. When the correct substrate binds to the active site, the enzyme catalyzes a particular reaction and releases new products. Substrates that don't match the shape of the enzyme's active site usually won't be affected by the enzyme. Enzymes are proteins, which are in turn polymers of amino acids. The sequence of amino acids in an enzyme, as well as the three-dimensional structure of the polypeptide chain, are essential for determining the enzyme's functionality. I hope that helps. Good luck!
- Q: what is the difference between enzyme and catalyst?
- Enzymes and catalysts both affect the rate of a reaction. The difference between catalysts and enzymes is that while catalysts are inorganic compounds, enzymes are largely organic in nature and are bio-catalysts. Even though all known enzymes are catalysts, all catalysts are not enzymes. Moreover, catalysts and enzymes are not consumed in the reactions they catalyze. Catalysts are low molecular weight componds, enzymes are high molecular globular proteins. Catalysts are inorganic, enzymes are organic. Catalyst reaction rates are slower (usually) than enzyme reaction rates. Catalysts are not generally specific - enzymes are VERY specific. Catalysts increase or decrease the rate of a chemical reaction, enzymes are proteins that incrase the rate of chemical reactions & convert the substrate into product. There are 2 types of catalysts - (positive & negative), and the 2 types of enzymes are activation enzymes and inhibitory enzymes. Catalysts are simple inorganic molecules, while enzymes are complex proteins.
- Q: Does increasing the amount of catalyst added to, say, a solution of Hydrogen Peroxide, make the rate of reaction go faster. Is the rate of reaction directly proportional to the amount of catalyst added to the solution? Or does the experiment go at the same rate regardless of how much catalyst there is? Thanks would really appreciate some answers. - Sarah
- Catalyst do not participate in the reaction but it speeds up the reaction. If you increase the amount of catalyst from the required amount, it would somehow negates its positive response or it would result in producing another product.
- Q: Is it not the rate to accelerate the addition of the catalyst to the catalyst, and that is why the balance does not move
- In the chemical equilibrium, after adding the catalyst, the positive and negative reaction rate increases equally, but the positive reaction rate is still equal to the reverse reaction rate, so the balance does not move
- Q: give an example of how a catalysts speeds up the rate of reaction?? thank you!!?
- Catalysts speed up a reaction, but at the end of it, it's chemically unchanged. You usually have the same mass at the end of the reaction. For example.. Consider the decomposition of Hydrogen Peroxide: 2H2O2 -2H2O + O2 I hope you got how to represent it =D So.. This reaction is very slow. You can try it out in the lab. So when we add a catalyst, the reaction speeds up. The catalyst used here is MnO2.. Manganese dioxide. Well.. The Enzymes in our body are also Catalysts. They speed up the Biological Reactions taking place inside out body. I hope this answers your question. :) Cheers
