In the reaction 2HgO(s) → 2Hg(l) + O₂(g) we measure the evolution of gas to determine the rate of reaction. At the beginning of the reaction (at 0 minutes), 0.020 L of O₂ is present. After 15 minutes the volume of O₂ is 0.35 L. What is the rate of reaction?

Question

Quizplus · Accepted Answer

The rate of reaction is calculated by the change in volume of O₂ over time: (0.35 L - 0.020 L) / 15 min = 0.022 L/min.
