Hydrogen peroxide (H2O2) decomposes in the presence of a catalyst to form liquid water and oxygen gas. The catalyst is added to 5.00 mL of a hydrogen peroxide solution at 25.0°C, and 49.5 mL of gas is collected over water at a total pressure of 763.8 mmHg. Q1: Write a balanced chemical equation for the reaction. (Note: catalysts do not appear in the balanced chemical equation) Q2: Look up the vapor pressure of water under these conditions (helpful link 2 ). and calculate the partial pressure of oxygen collected over the water?
