The rate law, rate constant, and reactant concentrations for the reaction of nitrogen dioxide with oxygen are given. What is the rate of the reaction under these conditions? R = k[NO]2[O2], k = 7,000 M-2 • s-1

[NO] = 0.040 M, [O2] = 0.060 M

A. R = 7,000 M-2 • s-1

B. R = 16.8 s-1

C. R = 0.672 M • s-1

D. R = 0.040 M2 • s-1
