The combustion of ethylene proceeds by the reaction C₂H₄(g) + 3O₂(g) → 2CO₂(g) + 2H₂O(g)
When the rate of disappearance of O₂ is 0.28 mol L^-1 s^-1, the rate of appearance of CO₂ is ________
Mol L^-1 s^-1.

From the stoichiometry of the reaction, we can see that 3 moles of O2 are consumed for every 2 moles of CO2 produced. Therefore, the rate of appearance of CO2 is 2/3 times the rate of disappearance of O2. Thus, the rate of appearance of CO2 is 2/3 * 0.28 mol L-1 s-1 = 0.19 mol L-1 s-1.
