Given the overall reaction: 2NO2 (g) -> 2NO (g) + O2 (g) and reaction mechanism: NO2 (g) -> N (g) + O2 (g), N (g) + NO2 (g) -> N2O2 (g), N2O2 (g) -> 2NO (g) pick the TWO TRUE statements. 1) Even if the elementary reactions sum to produce the overall reaction and the observed rate equals the predicted rate (from the reaction mechanism), the reaction mechanism may still not be valid. 2) If the second step is the slowest step, the reaction is first order in terms of oxygen. 3) From the overall reaction equation, we know that the rate must be second order in terms of nitrogen dioxide. 4) The reaction mechanism is not valid because the elementary steps do not sum to produce the overall reaction. 5) If the first elementary step is the slowest step, the reaction rate is first order in terms of nitrogen dioxide. 6) The nitrogen atoms in the reaction mechanism are an example of a homogeneous catalyst. 7) There is one reaction intermediate in the reaction mechanism.
