2. The rate law for the reaction: $NH_4^+(aq) + NO_2^-(aq) \rightarrow N_2(g) + H_2O(l)$ Is given by: Rate = $k(NH_4^+)(NO_2^-)$. At a certain temperature, the rate constant, $k = 4.00 \times 10^{-4} mol^{-1}Ls^{-1}$. a) What are the chemical names of the reactants? b) What are the (formal) oxidation states of nitrogen in each of the species in the reaction? c) Calculate the rate of reaction if $(NH_4^+) = 0.291 mol L^{-1}$ and $(NO_2^-) = 0.240 mol L^{-1}$. Make sure you have the correct units.
