🤓 Based on our data, we think this question is relevant for Professor Costanza's class at USF.
For the decomposition of hydrogen peroxide reaction below, the reaction is slow unless a catalyst is present.
2H2O2(aq) → 2H 2O(l) + O 2(g)
A. If a catalyst is added to 154 mL of 0.882 M H 2O 2(aq), how many moles of O 2(g) are produced, assuming the reaction goes to completion?
B. The oxygen gas from the above procedure was collected and dried to remove water vapor. The volume of O2(g) was 726 mL at 23.9°C and 735 mmHg. Determine the amount (moles) of O 2 gas collected.
C. What was the percent yield for the reaction?
D. Why was it necessary to remove the water vapor?
