(24pts) Calculations
For all three experiments plot the volume of O2 evolved in mL (on the y-axis) versus time in minutes (on the x-axis). Clearly label each experiment's plot and/or use a different color for each. Determine each initial rate of reaction (slope of the tangent at the beginning of the reaction). Zero time corresponds to the first volume reading at 2.0 mLyou must have entered your data this way during data entry. Label your axes so that your actual plotting encompasses at least half of your graph paper in each direction.
Concentration of H2O2 stock solution: 1.014 M
Concentration of KI stock solution: 0.10 M
