Title: Would lowering the temperature of a chemical reaction increase the time a molecular collision would take?
Post by: smooch92 on Nov 19, 2012
Also, would lowering the temperature of a chemical reaction cause the kinetic energy of the particles to decrease?

yes and yes

Increase in heat  is inversely related to an decrease in reaction time.

Becuase when you increase heat you speed up the reaction and therefore the reaction takes less time.

Lowering the temperature would decrease the number of collisions, and decrease the energy of each collision (thus answering your second question as yes) but the time of molecular collision--i.e., the duration of the collision?? This time is almost infinitesimally small; and the temperature has no real relevance on the duration of the collision -- so the answer to your first question is actually no; however, I am not sure if that is what you were truly asking.

the second is the reason of the first

yes. because lowering the temperature means that the molecules would have less kinetic energy so they would not move around as much to cause collision between the molecules and the answer to your second question is yes.
