The reaction 2NO(g) + O2(g) 2NO2(g) is second order in NO andfirst order in O2. When [NO] = 1.6 M and [O2] = 1.9 M, the observedrate of the reaction is 0.00045235 M/s. (a) What is the value ofthe rate constant? 9.299e-5 Correct: Your answer is correct. (b)What are the units of the rate constant? M-1s-1 M3s M1s-1 M-3s-1M-2s-1 M-1s-2 The rate constant has no unit. s-1 M0s-1 M-1 Correct:Your answer is correct. (c) What would happen to the rate if theconcentration of NO were increased by a factor of 3.9? The rate ofthe reaction would increase The rate of the reaction would decreaseCorrect: Your answer is correct. By what factor would the rate ofreaction increase? _______ (d) What is the rate of reaction when[NO] = 0.1 M and [O2] = 0.43 M? _______M/s
