- Q: why is palladium/platinum a good catalyst?
- Palladium and platinum can form partial bonds with other molecules. By forming these partial bonds, the bond in the actual molecule gets weaker and weaker and hence, the bond becomes easier to break. Let's say for example a hydrogen molecule. There is a single bond between the 2 hydrogen atoms. Platinum/palladium will form partial bonds with the 2 hydrogen atoms. By doing so, the single bond BETWEEN THE 2 HYDROGEN ATOMS gets weaker and weaker. Hence, a smaller amount of energy is needed to break the bond between the 2 hydrogen atoms (the hydrogen molecule). As the amount of energy needed to overcome the bond between the 2 hydrogen atoms gets smaller, we say the activation energy for the reaction has been reduced. Hence, a greater amount of bonds in hydrogen molecules can be broken in a smaller time, and therefore, we say palladium/platinum has catalysed the reaction.
- Q: what is a catalyst ?
- A substance which initiate the rate of chemical reaction without undergoing any change by itself till the end of the reaction.
- Q: Please help me
- enzymes are like chemical scissors that break up starch inside your body they work best at 37'c which is body temperatur i think they are in the stomach? don't know for sure hope this helped as for catalysts i dont know
- 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: about 1-3 sentences on this will do thank you
- a catalyst is something that makes a reaction go faster than it normally would. An enzyme is a catalyst; it has all the parts for the reaction on it and help organic materials break down or transfer energy or whatever reaction it needs.
- Q: in my 99 ram 2500 v8 5.9 that code came up, not sure what to do about it or what it could be any ideas or help with be great thanks
- DTC P0430 Catalyst System Low Efficiency Bank 2 Circuit Description In order to maintain a reasonably low emissions of Hydrocarbons (HC), Carbon Monoxide (CO), and Oxides of Nitrogen (NOx), the engine controls system uses a three-way catalytic converter. The catalyst within the converter promotes a chemical reaction which oxidizes the HC and CO present in the exhaust gas. This reaction converts them into harmless water vapor and Carbon Dioxide. The catalyst also reduces NOx, converting it to Nitrogen.
- Q: Will the catalyst in the chemical reaction be reduced?
- The amount of catalyst in the chemical reaction is not reduced, the catalyst is divided into a positive catalyst and a negative catalyst, the positive catalyst promotes the reaction, and the negative catalyst inhibits the reaction
- Q: What is the difference between biological and chemical catalysts?
- catalysts which catalyze the chemical reactions taking place in human body such as enzymes are called bio-catalyst and other one's which are generally used in laboratory by chemists for multiple type of reactions are chemical ctalysts
- Q: Why can some catalysts be reused in (chemistry)?
- Because the catalyst in the chemical reaction before and after the quality and chemical properties have not changed, so in the chemical reaction can be reused.
- Q: The catalyst can change the chemical reaction process, why is it wrong?
- The catalyst can change the chemical reaction rate
