How does the concentration affect the rate of a reaction?
In this investigation I will be investigating to see whether the concentration affects the rate of a reaction. To see if the concentration does affect the rate of a reaction I will be reacting various HCL strengths with Na2S2O3 to see if the concentration affects the rate the two substances react. Also in this investigation I will be looking into see if there are any states the substance should be in that would affect the rate of reaction.
The concentration of a substance is how strong the substance is. Normally the higher the concentration is of the substance. The stronger the substance is. However when conducting an experiment you can change the concentration of the substance to speed up or slow down the rate of a reaction. If you increase the concentration from 1M to 5M in a reaction then this increases the chances of particles colliding into one another, which would speed up the rate of a reaction. This means that if you increase the concentration of a substance in any reaction then the reaction should happen faster then before. The experiment I will be conducting to see if the concentration does affect the rate of a reaction is HCL with Na2S2O3. I will be reacting various amount of strengths of HCL with Na2S2O3. To conduct this investigation I will be using the following equipment:
