In this lab experience, students carry out an investigation to determine what leads to a successful collision between particles in a chemical reaction. “Particles” will be “collided” to determine the effects of concentration on the success rate of collisions. Students should come to understand that increasing the concentration of particles increases the success rate of collisions. Also, increasing the temperature of the particles increases the success rate of collisions.
Safety:
Before conducting the lab, review the safety precautions on the student page with the class. Then discuss any safety precautions that are specific to your science laboratory or classroom.
