The balanced reaction equation for all three of these was 2H2O2 → 2H2O + O2(g). The first was a solution of 10 mL 0.1 M KI, 15 mL DI water, 5 mL 3% H2O2. The reaction started out at 23.0C and⁰ended at 23.0C as well. The second was a solution of 10 mL 0.1 M KI, 10 mL DI water,⁰10 mL 3% H2O2. This reaction also started out at 23.0C and also ended at 23.0C. The⁰⁰third was a solution of 20 mL 0.1 M KI, 5 mL DI water, 5 mL 3% H2O2@ 23.0C. This⁰reaction also started out at 23.0C and also ended at 23.0C. The reason there was three⁰⁰reactions is because we needed three equations to solve for two unknown variables. In this case the equations were obtained from linear regressions of the graphs of the volume of oxygen gas collected vs. time and the two variables we had to solve for were the
