the sodium thiosulfate melts; at 215 degrees C‚ it loses all its five molecules of water; and above 220 degrees C‚ it is converted into sodium tetrasulfide. The collision theory briefly: For a reaction to occur particles have to collide with each other. Only a small percent result in a reaction. This is due to the energy barrier to overcome. Only particles with enough energy to overcome the barrier will react after colliding. The minimum energy that a particle must have to overcome the barrier is called
