07.04 equilibrium: hands-on equilibrium demonstration lab part iii follows a similar procedure as part i and part ii, except you will be adding additional candies to the activity. start with 40 candies on the reactant side of the paper. for each round, half of the candies that were on the reactant (r) side of the paper from the last round should be moved to the product side. one-fourth of the candies that were on the product (p) side of the paper from the last round should be moved to the reactant side. (if you end up with a decimal for the number to exchange, round up.) at the end of each round, count the number of candies on each side of the paper and keep track of the numbers in a data table. after five rounds, add 40 more candies to the reactant side of the paper. continue following the instructions in step 2 with this new amount of candy (total of 80 pieces of candy) for an additional 10 rounds. at the end of 15 total rounds, calculate the ratio (ratio = p/r) of products to reactants.
