Investigate how the change in concentration affects the rate of reaction between sodium thiosulphate and hydrochloric acid Introduction I am trying to find out how the change in concentration affects the rate of reaction between sodium thiosulphate and hydrochloric acid. I predict that the higher the concentration of sodium of thiosulphate, the quicker the rate of reaction will be between the two substances. The scientific reason for my prediction is due to the collision theory. The collision theory is, that in order for chemicals to react they must come into contact with each other (collide). However, not all collisions result in chemical reactions as sometimes the particles just bounce off each other. The particles must have sufficient energy when they collide to react. If you increase the number of collisions, you increase the rate of reaction. Therefore, a higher concentration means a greater number of collisions.
