P18A 2 Nitrogen dioxide reacts bimolecularly in the gas phase according to NO, + NO, NO+NO+O. The temperature dependence of the second- order rate constant for the rate law d[P]/dt = k [NO]' is given below. What are the steric factor and the reactive cross-section for the reaction? T/K 600 700 800 1000 k/(cm'mol's') 4.6 x 10 9.7 x 10 1.3 x 10 3.1 x 10 Take 0 = 0.60 nm
