Question

Reaction rate depends on how often molecules come into contact with each other, the way in which they come together, and the amount of energy they have when they come in contact.
Which of the following factors would you expect to affect the way in which molecules affect each other?
A) volume
B) catalysts
C) pressure
D) temperature

Answer 1

The most appropriate answer is D ! temperature !

as when temperature increases KE increases and the collision factor and frequency increases !

Answer 2

I know that the volume wouldn't have much affect because putting the 2 molecules together would cause the volumes density. I believe it would be the catalyst. I'm not completely sure because I haven't taken science in soo long.
