Q:What is the superiority of the catalyst compared to the stoichiometric reagent?
Mildness: means that the chemical reaction catalyzed by the enzyme is generally carried out under relatively mild conditions
Q:All high school chemistry uses sulfuric acid as a catalyst for the reaction
Esterification reaction (dehydration), nitration (dehydration, concentrated nitric acid), carbonation reaction or dehydration reaction (organic matter in sulfuric acid blackening, dehydrating agent), sulfonation reaction (dehydrating agent), ethylene (dehydrating agent).
Q:Final Fantasy XIII: Do I need to be worried about accidently using a component that is a catalyst?
catalyst's cannot be used apart from transforming items. They will be greyed out at all other times. They always say in the description can be used as a catalyst as well. btw, are you using 36 sturdy bones or vibrance ooze to get the 3x multiplyer strait up? oh yeah, never ever use any item at all that says can be sold for a premium. Always sell those items, they are worth lots of money. And when you start buying components, only ever buy particle accelerator, perfect conductor or ultra compact reactor. Perfect conductor gives least bang for $$$ out of the 3, whereas ultra compact reactor gives most bang for $$$. And the sturdy bones and vibrance ooze for multiplyer purposes. Hope this helped :)
Q:The size of △ H in the thermochemical reaction equation is related to the use and unused catalyst
There is no relationship between the catalyst can only change the reaction rate
Q:Why does the chemical and chemical properties change before and after the reaction?
Definition: According to the definition proposed by IUPAC in 1981, the catalyst is a substance that accelerates the rate of the reaction without changing the standard Gibbs free enthalpy change of the reaction. This effect is called catalysis. Involving the presentation of the catalyst for the catalytic reaction
Q:What are catalysts and enzymes?
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:What is positive and negative catalyst in chemistry?
Negative catalysts are, on the other hand, slowing down the positive reaction rate at the same time
Q:What is the meaning of catalyst in chemistry?
In the chemical reaction can change the reaction rate of chemical reaction (increase or decrease) without changing the chemical balance, and its own quality and chemical properties in the chemical reaction before and after the material did not change the catalyst.
Q:Which of the following are true about catalysts?
1, 3, 5, 6, 7. 2 is incorrect, catalysts are written above the reaction arrow. 4 is incorrect, catalysts decrease the activation energy thus increasing the rate of reaction (see 7) 8 is incorrect, catalysts are not used up (or if they are, they are also regenerated by a different reaction so that they maintain a constant concentration). edit: about 5, yes i think the answer below is correct, 5 is false actually. catalysts speed up both the forward and the reverse reaction so the equilibrium constant is unchanged. however, 1 is true i think: catalysts can provide a lower energy pathway by way of bringing the reactants together in the correct orientation (rather than random orientations).
Q:Question about catalysts and their function.?
Catalysts, as enzymes, only change the activation energy (the energy the compound needs to gain to transform into products), they don't change the Gibbs energy values of reactants nor products. Therefore, if the delta G of the reaction is positive, it'll still need free energy to complete. They make a reaction complete faster than in normal conditions, but don't change the actual possibility for that reaction to happen. In the human body, a lot of reactions of catabolism have a positive G value and these reactions needs to get energy from other coupled reactions that have a negative value, so the total value is still negative. Many of them use hydrolysis of ATP to provide that energy, as its hydrolysis is about -30 kJ/mol in physiological conditions. I don't know what class you're in to ask this question, so can't really know if this answer is too simple or complicated for u... sorry in advance! Joël
