Q:Can manganese dioxide be used as a catalyst for various chemical reactions?
Catalyst in the reaction process involved in the reaction, after the completion of the reaction was reduced to the original ingredients.For example: heating decomposition of potassium permanganate when added potassium permanganate potassium potassium permanganate decomposition process, the potassium permanganate is involved in the reaction, The specific way is not clear.Finally, the occurrence of potassium permanganate before and after the reaction of the catalyst changes in morphology, particles into powder, powder particles and so on.
Q:Chemical Reactions Under what circumstances the catalyst accelerates the reaction
First, more than ninety-nine percent of the catalyst is accelerating the reaction, and if the catalyst kinetics reduces the energy barrier of the reaction, the reaction will naturally accelerate.
Q:what is a catalyst?
a catalyst is a substance that affects the rate of rxn without actually being consumed in the rxns . a catalyst doesnt become a part of the products. catalystss are of two types 1 POSITIVE CATALYST . it increases the rate of rxn . that is the products are formed faster . eg sunlight in a photochemical rxn is a positive catalyst 2 NEGATIVE CATALYST - which slow down a rxn . like addition of glyceriene to hydrogen peroxide slows down its decomposition
Q:Chemical reactions in the presence of impurities will cause catalyst poisoning
This is in the chemical balance, but also alone
Q:On the issue of chemical balance and catalyst
If the chemical equilibrium does not move, then only the catalyst can change the time to reach equilibrium. If you change the temperature, pressure, it will affect the chemical balance.
Q:Catalyst & an exothermic reaction?
Catalysts work by providing an (alternative) mechanism involving a different transition state and lower activation energy. The effect of this is that more molecular collisions have the energy needed to reach the transition state. Hence, catalysts can perform reactions that, albeit thermodynamically feasible, would not run without the presence of a catalyst, or perform them much faster, more specific, or at lower temperatures. This can be observed on a Boltzmann distribution and energy profile diagram. This means that catalysts reduce the amount of energy needed to start a chemical 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
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:Does a catalyst have an effect on the Gibbs free energy of a reaction?
A catalyst can change the activation energy not the Gibbs energy. The Gibbs energy is the energy difference between the initial state and final state. A catalyst cannot change that. Imagine you are driving from school to home. How you drive do not change the height difference between the school and your home. However, a catalyst can change your path which can change the routine you drive from school to home. So if there is a hill in between your school and you home, you have the choice to drive through it or drive around. Here is a picture: upload.wikimedia.org/wikipedia/co... A catalyst can change the height of the barrier, but cannot alter the initial or final state.
Q:What is a catalyst/catalase? help?
Catalysts and catalase are two different things, and the definitions that you listed are correct. A catalyst is something that speeds up the rate of a chemical reaction. Many chemical reactions occur naturally and do not require any energy, but they occur so slowly that they are not useful, and catalysts can be used in cases like this to speed up the process. For example iron metal exposed to oxygen and water turns to rust, but if you need a lot of rust by tomorrow, leaving a chunk of iron out in the rain is not a practical solution because it will take too long to convert all that iron metal into rust.
Q:Will the catalyst change the reaction rate in the chemical reaction?
Many of the catalysts are specific in varying degrees, and when added to the chemical reaction system that it can catalyze, it must change the rate of chemical reaction, and of course both positively and negatively catalyzed. Chemical reaction rate, it can not be called a catalyst.
