- Q:okay im doing a project for my classroom about catalyst and i have to draw a picture but when i looked up on google i just saw a bunch of random stuff and a couple were metal so thats why im asking this question. :)
- A catalyst is something that enables a process to take place without being part of said process itself, such as in a chemical reaction.
- Q:What is the catalyst condition in the chemical equation?
- On the middle of the equal sign or arrow above ah ~
- Q:Could you please explain it, i know they increase reaction rates but how?
- A catalyst lowers the activation energy (the minimum amount of energy needed for a reaction to take place). This means that the particles can react with less energy than they needed before the catalyst was added. (Think about it: if the government lowered the legal age to buy cigarettes, then more people could legally buy cigarettes. Similarly, if we lower the amount of energy needed for particles to react, then more particles can react). Also, a catalyst provides a surface on which the reaction can take place. This increases the number of collisions between the particles of the substances that are reacting.
- Q:How the catalyst accelerates the chemical reaction
- Reduced the activation energy required to reflect
- Q:Especially how can i explain the experiment with a paper and 2 paperclips with the paper acting as the catalyst.
- A catalyst is something that allows a reaction to occur but is not actually used up in the reaction. It merely provides the surface on which the chemicals react. There is a demo using two paper clips and a piece of paper. The paper is folded and the two clips are attached to the paper. When the free ends of the paper are pulled apart the two paper clips somehow overlap each other and become joined. It is a good demo for a catalyst, but I cannot explain how to fold the paper.
- Q:How does active charcoal catalyze in some chemical reactions?
- Activated carbon is generally in the catalytic reaction to do more carriers, has not yet seen its catalyst to report.
- Q:and what type of macromolecule are they made of? thanks!
- Enzymes okorder /...
- Q:High school stage which organic chemical reactions do not use catalyst
- Aldehyde and silver ammonia solution reaction, and the new system of Cu (OH) 2 reaction.
- Q:i keep messing up on those 2 simple things haha i would apprecaite some help.
- enzymes help biochemical reactions proceed at a faster rate than normal in a physiological system, catalysts or sometimes referred to as subunits, metals and other ligands, bind enzymes, and can have a positive and negative effect on the rate of a reaction. search them on wikipedia!
- Q:In the chemical reaction, the rate of decomposition reaction is related to the quality of the catalyst?
