,the rate of disappearance of C₂H₄ is ________ 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 ,the rate of disappearance of C2H4 is ________ A) 0.087 B) 0.043 C) 0.39 D) 0.20 E) 0.26

Quizplus · Accepted Answer

The balanced chemical equation shows that the ratio of the disappearance of O2 to C2H4 is 3:1. This means that for every 3 moles of O2 disappearing, 1 mole of C2H4 disappears. Therefore, if the rate of disappearance of O2 is 0.13 M/s, the rate of disappearance of C2H4 is (0.13 M/s) / 3 = 0.043 M/s. Therefore, the answer is choice B.

The Combustion of Ethylene Proceeds by the Reaction C2H4 (G)

The Combustion of Ethylene Proceeds by the Reaction C₂H₄ (G)
