Increasing temp causes increased molecule movment in sample 2
Answer: increases
Explanation:
Increase in the temperature of a reaction system will cause the molecules of the reactants to possess higher kinetic energy which they would use to travel more randomly in the system, colliding more frequently with other excited molecules and with the wall of the containing vessel.
Thus, if temperature is increased, the number of collision per second also increases.
