On a molecular level, how does decreasing the temperature affect the rate of a reaction?

On a molecular level, how does decreasing the temperature affect the rate of a reaction?





A


Molecular speed increases, and more effective collisions will take place. The reaction will be faster.





B


Molecular speed increases, and fewer effective collisions will take place. The reaction will be slower.





C


Molecular speed slows, and fewer effective collisions will take place. The reaction will be slower.





D


Molecular speed slows, and more effective collisions will take place. The reaction will be faster.
