The following mechanism has been proposed for the gas-phase reaction of chloroform (CHCl3) and chlorine. Cl2 ⇌ 2Cl (fast, reversible) Cl + CHCl3 → HCl + CCl3 (slow) Cl + CCl3 → CCl4 (fast) What rate law does this mechanism predict? (Choose from the list below and enter your answers in alphabetical order, e. g. ABC ). A)k G) [CCl3]1/2 M) [HCl]2 B) [Cl] H) [HCl]1/2 N) [Cl2]2 C) [CHCl3] I) [Cl2]1/2 O) [Cl]2 D) [CCl3] J) [Cl]1/2 P) [CHCl3]2 E) [HCl] K) [CHCl3]1/2 F) [Cl2] L) [CCl3]2

Rate = K [CHCl₃] [Cl₂]⁰•⁵

Rate = ACI (from the list of options)

Explanation:

Cl₂ ⇌ 2Cl (fast, reversible)

Cl + CHCl₃ → HCl + CCl₃ (slow)

Cl + CCl₃ → CCl₄ (fast)

The rate determining step is the slow step

Hence

Rate = k [Cl] [CHCl₃]

Then, we can write the rate equations for the other elemestart steps

Step 1

rate = k₁ [Cl₂] = k₁' [Cl]²

[Cl] = √{(k₁/k₁')} √{[Cl₂]}

Substituting for [Cl] in the rate determining step

Rate = k [Cl] [CHCl₃]

= k√{(k₁/k₁')} √{[Cl₂]} [CHCl₃]

k√{(k₁/k₁') = K

Rate = K√{[Cl₂]} [CHCl₃]

Rate = K [CHCl₃] [Cl₂]⁰•⁵

Option A = K

Option C = [CHCl₃]

Option I = [Cl₂]⁰•⁵

Hence, Rate = ACI

Hope this Helps!!!

i have a feeling this is a gay person trolling to make straights look bad.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
