- Q: Before and after the reaction, the chemical properties and quality of the water did not change, and the water was the catalyst
- Dry aluminum powder and iodine does not react, there is water to react.
- 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: On the issue of chemical balance and catalyst
- The catalyst also changes the forward and reverse reaction rate.
- Q: Does the catalyst participate in chemical reactions?
- The catalyst does not participate in the chemical reaction, it only plays an auxiliary role.
- Q: Co and No form a chemical equation for Co2 and No2 under the action of a catalyst
- Write the catalyst on the horizontal line, where NO is the oxidant and CO is the reducing agent
- Q: Could you please explain it, i know they increase reaction rates but how?
- A catalyst lowers the activation energy (the minimum amount of energy needed for a reaction to take place). This means that the particles can react with less energy than they needed before the catalyst was added. (Think about it: if the government lowered the legal age to buy cigarettes, then more people could legally buy cigarettes. Similarly, if we lower the amount of energy needed for particles to react, then more particles can react). Also, a catalyst provides a surface on which the reaction can take place. This increases the number of collisions between the particles of the substances that are reacting.
- Q: In the catalyst and light conditions to break down the water to get the chemical equation of hydrogen
- 2H2O = (light or catalyst) 2H2 ↑ + O2 ↑
- Q: I know that a species that does not appear in the chemical equation may also affect the rate of a reaction - e.g. a catalyst. But does that mean the catalyst can be present in the rate equation, and if so are catalysts always present in the rate equation?
- Any reaction with a finite amount of reactants has a half-life, whether it's first order, second order, zero order or complex order. The half-life (t?) is defined as the time taken for the reaction to go half-way to completion. If the reaction is: A + B ---products and A is in excess, then t? will be the time taken for half of B to be used up. For all reactions, then, you get a decay curve. For zero-order reactions, this 'curve' is a straight line, but for all other orders, the curve is an actual curve and it is quite difficult to distinguish, by visual inspection alone, whether it is exponential (indicating a first-order reaction) or hyperbolic (indicating a second or higher order reaction).
- Q: Chemical reaction plus catalyst on the △ H no effect
- Since the addition of the catalyst only accelerates the reaction process and does not have an effect on the reaction product and the reactants
- Q: What are the characteristics of the catalyst in the catalytic reaction?
- The role of the catalyst in the chemical reaction is to change the rate of chemical reaction, and its own quality and chemical properties do not change.
