Which of the following statements about the collision theory is correct?
Ineffective collision brings about chemical reaction
All collisions bring about reactions
The rate of reaction is proportional to the number of effective collisions
Collision of molecules will split the molecules to react
Vysvětlení
The rate of reaction is proportional to the number of effective collisions. This means that if the number of collisions increases, the rate of reaction will also increase. These successful collisions are known as effective collisions. The rate of reaction is directly proportional to the number of effective collisions between reactant molecules. In other words, the more frequent and successful the collisions, the faster the rate of the reaction.
