The combustion of ethylene proceeds by the reaction C₂H₄ (g) + 3O₂ (g) → 2CO₂ (g) + 2H₂O (g)
When the rate of disappearance of O₂ is 0.13 M s^-1, the rate of appearance of CO₂ is ________ M s^-1.

Question

Quizplus · Accepted Answer

The stoichiometry of the reaction shows that 3 moles of O₂ produce 2 moles of CO₂. Therefore, the rate of appearance of CO₂ is (2/3) times the rate of disappearance of O₂: (2/3) * 0.13 M s⁻¹ = 0.087 M s⁻¹.
