(A) rate = k[NO][Br2] (B) rate = k[NO]2[Br2] (C) rate = k[NO][NOBr2] (D) rate = k[NO]268. At 100 °C, nitrogen dioxide decomposes according to the following equation NO2(g) -------> NO(g) + 1/2 O2(g) The reaction is studied by following the change of the NO2concentration with time. The following three graphs were obtained. Which of the following statements is false? 69. The rate of an elementary reaction A(g) + B(g) -------> C(g) + D(g) has been studied as a function of temperature between 5000 and 18000 K. The following data were obtained for the rate constant: T (K) k (M/sec) 5000 5.49 x 10610000 9.86 x 10815000 5.57 x 10918000 9.92 x 109Calculate the activation energy for the reaction.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
