Question

Determine the rate law and the value of k for the following reaction using the data provided.

2 NO(g) + O2(g) ----------> 2 NO2(g)
[NO]i (M) [O2]i (M) Initial Rate (M-1s-1)
0.030 0.0055 8.55 x 10^-3
0.030 0.0110 1.71 x 10^-2
0.060 0.0055 3.42 x 10^-2
Options:
A. Rate = 57 M-1s-1[NO][O2]
B. Rate = 3.8 M-1/2s-1[NO][O2]1/2
C. Rate = 3.1 x 10^5 M-3s-1[NO]2[O2]2
D. Rate = 1.7x10^3 M-2s–1[NO]2[O2]
