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.

It is C.





Lower temperature makes molecules speed decrease (because it is that speeding that makes temperature high or low).





Fewer effective collisions because the slow speed ones have less energy to give up at the collision.
Reply:c. makes the most sense
Reply:c is the answer.
Reply:option c) reducing temp reduces kinetic energy leading to less motion of molecules,,,,lesser collisions......and thus a slower reaction.
Reply:definelty c, the reaction will be slower


I had a question like that on one of my exams, im a chemistry major
