As the temperature rises, molecules move faster and collide more vigorously, greatly increasing the likelihood of bond breakage upon collision. The best way to solve traffic jams is by using public transportation because it will be efficient, economical, and reliable. An increase in the reactant concentration. TRUE B.)
