How can the number of effective collisions be increased? OAdd more water because then there will be more room for the molecules to get oriented correctly. Be sure you are mixing two solids, because then the particles will have more kinetic energy. Lower the temperature because that way the collision will last longer. Increase the total number of collisions.
