Consider the gas-phase reaction between nitric oxide and oxygen showing the initial concentrations of the reactants at a certain temperature, $\mathrm{T}$ $2\mathrm{NO}(\mathrm{g})+{\mathrm{O}}_2(\mathrm{g})?2{\mathrm{NO}}_2(\mathrm{g})$ 1. Determine the order with respect to $\mathrm{NO}$, and outline reasoning. 2. Determine the order with respect to ${\mathrm{O}}_2$, and outline reasoning. 3. Calculate the rate constant and give its units at this temperature. 4. Calculate the initial rate of disappearance of ${\mathrm{O}}_2(\mathrm{g})$ in units of $\mathrm{M}?{\mathrm{s}}^{?1}$ for experiment 3. 5. If this reaction follows a two-step mechanism with the first step being $2\mathrm{NO}?{\mathrm{N}}_2{\mathrm{O}}_2$ (a). Write an equation for the second step of the mechanism. (b). Identify the rate determining step of this mechanism and outline your reasoning.
