The rate of a reaction is how quickly the reaction goes to completion. If two reactions have the same amount of reactant, increasing the rate does not increase the amount of product produced, it simply reduces the time that it takes to make the product. Using the internet, research the Reactant concentration factor below that affect the rate of a chemical reaction. 1. Reactant concentration (be very detailed add graphs to explain your details it should be 300 words) Your work should be written in complete sentences, and assume your audience is grade 11 chemistry students who do not understand this unit. Make sure all research is put into your own words!

Note: Show all calculations, follow the rules of significant figures, and box your final answer.
In the method of initial rates, only a small amount of reagent is used up (the change in concentration is small compared to the total concentration). The elapsed time is used to calculate the rate. Why is this more accurate than calculating the rate from the amount of time required to use up all of the reagent? (Hint: What happens to the rate as the concentration decreases?)
X 22. Which of the following 0/1 statements are correct? * An increase in temperature makes particles move slower, therefore slowing down a reaction An increase in concentration means there are less particles, which will make the reaction go faster Using smaller pieces of reactants will X increase the surface area making a reaction go slower If there is no catalyst added, the activation energy will be higher meaning the reaction will be slower
