 ____________________________________________________ The rate law for this reaction is rate = k[NH4+][NO2−].         NH4+(aq) + NO2−(aq) → N2(g) + 2 H2O(l) At a certain temperature the rate constant is 5.0 M−1 s−1. What is the rate of the reaction at this temperature when [NH4+] = 0.50 M and [NO2−] = 0.50 M?
