Experimental Procedure 50.0 mL of 0.882 M H₂O₂ and a platinum catalyst disc with a volume of 1.0 cm³ was placed in a test tube that had a total volume of 150.0 mL. The test tube was then immediately fitted with a pressure sensor and the increase in pressure due to the oxygen produced was monitored twice per minute for 3 minutes. This procedure was then repeated with 50.0 mL of 0.706 M H₂O2. Both experiments were conducted at a temperature of 25.0 °C. 2H2O2(aq) → O2(g) + 2H₂O (1) Experimental Data The following experimental data was collected. T = 25.00 °C [H₂O₂] = 0.882 M Time (s) P 0.00 30.00 60.00 90.00 120.00 150.00 180.00 oxygen (torr) 0 90 178 263 348 430 510 [H₂O₂] = 0.706 M Time (s) 0.00 30.00 60.00 90.00 120.00 150.00 180.00 P oxygen (torr) 0 72 142 211 278 344 408 3.
