1. For parts 1 and 2, Use the dilution equation to calculate the starting concentration of each reactant for each trial. (Hint: You know the concentration and volume of each reactant added, M1 and V1. For every trial, the total volume, V2, is 1.9 ml.) 2. Calculate the rate of each reaction for each reaction in parts 1 and 2 using. Average the times for repeat trials. For example if you have 2 trials for reaction 1A + 1B, average those times before calculating the reaction rate.
