What happens to the fraction of molecules able to collide successfully in a system when the system is cooled?
A) The fraction is not affected.
B) The fraction increases.
C) The fraction decreases.
D) There is not enough information to tell.
Cooled
The process of lowering temperature or the state of being less warm.
Successful Collisions
Interactions between reactant particles that result in a chemical reaction, dependent on factors like orientation and energy.
Molecules
Molecules are two or more atoms bonded together, forming the smallest fundamental units of a chemical compound that can take part in a chemical reaction.

Final Answer :
C
Explanation :
When a system is cooled, the kinetic energy of the molecules decreases, leading to fewer molecules having enough energy to overcome the activation energy barrier for a reaction. This results in a decrease in the fraction of molecules able to collide successfully.
