How does concentration affect the rate of reaction? Planning Experimental Procedures: Prediction: My prediction is that the higher the concentration of reactive substances in an experiment will reflect directly upon the rate of the reaction, in that it will be speeded up in comparison to an experiment with a lower concentration of reactive substance. My reasoning for this explanation is that the rate of reaction depends on how frequently the molecules of the reacting substances collide. A more concentrated substance has more molecules for a given volume than a more dilute substance. Because there are more molecules about, the frequency of successful collisions is greater, and the reactions happen faster. Diagram: Low Concentration High Concentration There are various factors affecting the rate of reaction that I need to take into consideration, these are: A) Temperature- I will conduct all the tests at room temperature on the same day because temperature has an effect on the rate of...
