1. What was your hypothesis? 2. Plot your data as drops of ascorbic acid vs. time. 3. As the concentration of ascorbic acid was increased, did the rate of the formation of the lodine starch complex Increase or decrease? Explain your answer in terms of the chemical reactions involved. 4. Was your hypothesis correct? 5. Make a general rule about the effects of concentration of reactants on reaction rates 6. For practice, the molecular formula for ascorbic acid is C6H806, and you used 6 g in this experiment, calculate the molarity of the ascorbic acid. Now calculate the concentration in moles per drop (assume 1 mL = 20 drops).
