- Q:put in a way that a freshman in high school can understand please =)
- Enzymes are actually biological catalysts composed of hundred of amino-acids, which are produced by living organisms. They are responsible for a number of reactions and biological activities in plants, animals, human beings and micro-organisms. There are also chemical catalysts that interact with other reactants and modify them without being changed themselves.
- 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.
- Q:Describe the role of a catalyst and a substrate in a chemical reaction.
- a catalyst lowers the activation energy of a reaction. By lowering the activation energy, the internal kinetic energy the reactants become sufficient for the reaction to occur on a much larger scale and thus appear faster. Without the catalyst, you would depend on the statistical probabilities of small numbers of reactant particles having enough internal kinetic energy to overcome the activation barrier. a substrate is merely the substance in the reaction being catalyzed
- Q:What is the catalyst condition in the chemical equation?
- On the middle of the equal sign or arrow above ah ~
- Q:Why is the catalyst in the chemical balance, the rate of change and balance?
- But the positive reaction rate is accelerated, but also speed up the reverse reaction rate, the two increase the same multiple, so the system is still in a stable state, the same balance.
- Q:Is it faster or slower? The What if you do not?
- Positive catalyst is to speed up the negative catalyst to slow down some reaction must be used to the catalyst otherwise difficult to react
- Q:Can you describe at least 4 ways a catalyst can lower the activation energy of a reaction?
- To see how a catalyst accelerates the reaction, we need to look at the potential energy diagram shown below which compares the non-catalytic and the catalytic reaction. For the non-catalytic reaction, the figure is simply the familiar way to visualize the Arrhenius equation: the reaction proceeds when A and B collide with succificient energy to overcome the activation barrier. The change in Gibbs free energy between reactants, A + B, and the product P is delta G. The catalytic reaction starts by bonding of the reactants A and B to the catalyst, in a spontaneous reaction. Hence, the formation of this complex is exothermic and the free energy is lowered. There then follows the reaction between A and B while they are bound to the catalyst. This step is associated with an activation energy; however, it is significantly lower than that for the uncatalyzed reaction. Finally, the product P seperates from the catalyst in an endothermic step. The energy diagram illustrates 4 ways the catalyst works : The catalyst offers an alternative path for the reaction that is energetically more favorable The activation energy of the catalytic reaction is significantly smaller than that of the uncatalyzed reaction; hence the rate of the catalytic reaction is much larger The overall change in free energy for the catalytic reaction equals that of the uncatalyzed reaction. Hence, the catalyst does not affect the equilibrium constant for the overall reaction. A catalyst cannot change the thermodynamics of a reaction but it can change the kinetics. The catalyst accelerates both the forward and the reverse reaction to the same extent. In other words, if a catalyst accelerates the formation of product P from A and B, it will do the same for the decomposition of P into A and B.

- Phosphoric acid or sulfuric acid, 280 to 300 ° C, 7 to 8 MPa
- Q:how do catalysts help in green chemistry?
- Catalysts allow more efficient conversion of products in irreversible reactions, or they allow for the faster attainment of equilibrium in equilibrium reactions, thereby reducing time, raw material waste and emissions. Also, because catalysts are reusable, they can be recycled.
