With high concentrations the rate of reaction will be fast. This is because according to the collision theory the more you increase the concentration of a substance then the rate of collision increases.

Scientific knowledge With high concentrations the rate of reaction will be fast. This is because according to the collision theory the more you increase the concentration of a substance then the rate of collision increases. If the solution is made more concentrated it means there are more particles of the reactant colliding with the water particles. Hence the collision between the sodium thiosulphate and the Hydrochloric acid particles becomes more likely. If a low concentration of sodium thiosulphate were used then there would be less collision. The more the collision with particles the faster the rate of reaction will be. Whereas with low concentrations the rate of reaction will be slow. With high concentrations there is more collision between the particles therefore they will react quickly and largely because the number of particles increase when the concentration is increased. Hence as the amount of solution is kept the same and...
