The following 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 7.4 Å~ 102 M-2s-1. What is the rate of reaction when the initial concentrations of NO and O2 are 0.030 M and 0.025 M, respectively?
2 NO(g) + O2(g) --> 2 NO2(g)
