• by giving them more energy

• by making them more available

What makes an effective collision?

• When molecules collide.
• When molecules collide with the proper orientation.
• When molecules collide with proper orientation and enough kinetic energy.
• High Temperature.

Why don't all collisions between particles cause a reaction?

• the particles also need to collide with a catalyst
• not all the particles collide with enough energy
• not all the particles collide at a high enough temperature
• the particles need to collide with each other twice
