Question

The reaction of NO and O2 produces NO2.
2 NO(g) + O2(g) 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 4.7 102 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 10-3 M/s
B.4.4 10-3 M/s
C.0.18 M/s
D.2.0 10-8 M/s
E.3.8 102 M/s
