When the rate of disappearance of

The combustion of ethylene proceeds by the reaction C<sub>2</sub>H<sub>4</sub>(g) + 3 O<sub>2</sub>(g) → 2 CO<sub>2</sub>(g) + 2 H<sub>2</sub>O(g) When the rate of disappearance of is 0.23 M s<sup>-1</sup>,the rate of disappearance of C<sub>2</sub>H<sub>4</sub> is ________ M s<sup>-1</sup>. A) 0.15 B) 0.077 C) 0.69 D) 0.35 E) 0.46

is 0.23 M s^-1,the rate of disappearance of C₂H₄ is ________ M s^-1.

Quizplus · Accepted Answer

From the balanced equation, the stoichiometry between O2 and C₂H₄ is 3:1. Therefore, the rate of the disappearance of C₂H₄ is one-third of the rate of the disappearance of O2. Rate of disappearance of O2 = 0.23 M s^-1 Rate of disappearance of C₂H₄ = (1/3) x 0.23 M s^-1 = 0.077 M s^-1 Therefore, the answer is B.

The Combustion of Ethylene Proceeds by the Reaction C2H4(g)+ 3
