- 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
- The rate constant of the reaction changes as the reaction proceeds.
- For an elementary reaction, the reaction order is same to the molecularity.
