Multiple Choice

The reaction of NO and O₂ produces NO₂.
2 NO(g) + O₂(g) $\to$ 2 NO₂(g)
The reaction is second-order with respect to NO(g) and first-order with respect to O₂(g) .At a given temperature,the rate constant,k,equals 4.7 $\times$ 10² M^-2s^-1.What is the rate of reaction when the initial concentrations of NO and O₂ are 0.025 M and 0.015 M,respectively?

A) 2.6 $\times$ 10^-3 M/s
B) 4.4 $\times$ 10^-3 M/s
C) 0.18 M/s
D) 2.0 $\times$ 10^-8 M/s
E) 3.8 $\times$ 10² M/s
