- Q:Which chemical reaction is added to the catalyst in order to slow down the reaction
- Edible oil added 0.01% to 0.02% gallate n-propyl ester, you can effectively prevent rancidity
- Q:Hydrogen and nitrogen in the high temperature and pressure and catalyst conditions for the synthesis of ammonia chemical equation
- 3H2 + N2 catalyst iron ---> 2NH3 conditions high temperature and high pressure
- Q:The beginning of the chemistry plus the catalyst and the plot without the Cuihua agent
- Activated molecular map
- 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:What is a catalyst?
- The catalyst plays a role in a variety of ways that are likely to temporarily alter the chemical changes associated with the reactants themselves, and may also only help to adsorb the physical changes in the reactants, but the reaction eventually becomes its own form The
- Q:Please help me
- A catalyst is a substance which is used to increase or decrease the rate of a reaction, without itself undergoing any chemical change. There are two types of catalysts, positive and negative. Positive catalysts are used to increase the rate of a reaction while negative catalysts are used to decreasing the rate of a reaction. Enzymes are proteins which act as catalysts in biochemical reactions. They operate between a certain pH level and temperature. If there is a change in pH level or temperature, their efficiency decreases.
- Q:Can Cuo react as a catalyst with H2O2, does its quality and chemical properties change?
- Can be, please, upstairs said wrong ... ... ... ... ... ... catalyst is not not to participate in the reaction, the second is because the essence of the catalyst is to participate in the reaction to accelerate the reaction rate of conversion, the catalyst after the reaction will be regenerated, and before and after conservation, quality and Chemical properties do not change. CuO is the catalyst for H2O2 reaction, and the catalytic effect of CuO is better than Mn02!
- Q:What are the catalysts?
- The catalyst is a substance that can change the rate of the reaction without changing the standard of the reaction Gibbs free, according to the definition of the International Pure and Applied Chemistry (IUPAC) in 1981, Enthalpy change. This action is called catalysis. The reaction involving the catalyst is a catalytic reaction. The catalyst will induce a chemical reaction to change, causing the chemical reaction to become faster or slower or to undergo a chemical reaction at a lower temperature The catalyst is also known as a catalyst in industry, and the composition, chemical properties and quality of the catalyst itself do not change before and after the reaction;
- 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
- If the reaction before the catalyst, you can speed up the reaction rate, that is to achieve the balance required to reduce the time, but to balance the system when the same concentration
- Q:hey people i need your help about my science lab report...the question on my paper says "what function the catalyst?....please help me on this one...i would really appreciate if you leave me answers....much mahalos to all you folkss...thanks
- A catalyst is a substance used to change the rate of a reaction. If it increases, it is posititve catalyst . Decreases means negative catalyst. If the reactants and catalyst are in same phase, it is homogenous catalysis, otherwise heterogenous. Any reaction to occur, the reactants have to combine to form an intermediate compound and then to product. This requires surpassment of a minimum amout of energy known as Ea- Activation energy. Catalyst decreased the Ea, so that , passing the barrier becomes easy and hence the speeding of the reaction.
