PLEASE HELP.What was your hypothesis? Plot your data as drops of ascorbic acid vs. time. As the concentration of ascorbic acid was increased, did the rate of the formation of the iodine-starch complex increase or decrease? Explain your answer in terms of the chemical reactions involved. Was your hypothesis correct? Make a general rule about the effects of concentration of reactants on reaction rates. For practice, the molecular formula for ascorbic acid is C6H8O6, 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).

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + Ā½o2(g) ā mgo(s) + 146 kcal/mole h2(g) + Ā½o2(g) ā h2o(g), Ī“h = -57.82 kcal/mole what type of reaction is represented by the previous two examples?
