- The rate of second-order reaction remains constant throughout the reaction.
- For an elementary reaction, the reaction order is same to the molecularity.
- If the reaction of 2A+B → C is a elementary reaction, which choice listed below is true? A: it is a second order reaction B: it is a slow reaction C: it is a second order reaction to B D: it is a second order reaction to A
内容
- 0
It is known that the chemical reaction A + B → C + D is a elementary reaction, then it can be inferred that the total order of this reaction is 2.
- 1
The rate constant of the reaction changes as the reaction proceeds.
- 2
The more negative the ∆G of a chemical reaction is, the higher the reaction rate is.
- 3
In a bimolecular reaction, if the Two molecules collide in the right angle, the reaction must happen.
- 4
For a given reaction, doubling the temperature will increase the reaction rate by () A: 2 B: 0.61 C: 2.7 D: 1.6
