Question

A student notices that a reaction takes place faster when the temperature is higher. Which best explains why this happens? (1 point)


At higher temperatures, the molecules collide more frequently.

The heat of the solution breaks apart chemical bonds.

As the particles move more quickly, they can more easily avoid each other.

Catalysts cannot be effective at high temperatures.

Answer 1

at higher temperatures, the molecules collide more frequently.

Answer 2

Answer:

At higher temperatures, the molecules collide more frequently.

Explanation:

The reason why reactions occur is effective collisions of molecules with each other. By effective collisions we mean to say that the collisions are occuring in proper orientation. When the temperature increases, molecules gain kinetic energy and more kinetic energy means the molecules will tend to move even more. If the molecules will have more movement then they will also have more propensity of colliding with each other. More collisions will ultimately result in increased likely hood of effective collisions. Therefore as compared to lower temperature, the reaction will speed up at higher temperature.
