Determine the Rate Law and the Value of K for the Following

question 82

Multiple Choice

Determine the rate law and the value of k for the following reaction using the data provided: CO(g) + Cl₂(g) → COCl₂(g) [CO]_i (M) [Cl₂]_i (M) Initial Rate (M¹ s^-1)
0) 25 0.40 0.696
0) 25 0.80 1.97
0) 50 0.80 3.94

• A) Rate = 11 M^-3/2 s^-1 [CO][Cl₂]^3/2
• B) Rate = 36 M^-1.8 s^-1 [CO][Cl₂]^2.8
• C) Rate = 17 M^-2 s^-1 [CO][Cl₂]²
• D) Rate = 4.4 M^-1/2 s^-1 [CO][Cl₂]^1/2
• E) Rate = 18 M^-3/2 s^-1 [CO]²[Cl₂]^1/2
