Ammonium ion (NH4+) reacts with nitrite ion (NO2–) to yield nitrogen gas and liquid water. The following initial rates of reaction have been measured for the given reactant concentrations. Expt. # [NH4+] (M) [NO2–] (M) Initial rate (M/h).
1 0.010 0.020 0.020
2 0.015 0.020 0.030
3 0.030 0.010 0.015.
Which of the following is the rate law (rate equation) for this reaction?
a. rate = k [NH4+]2 [NO2-]
b. rate = k [NH4+ ] [NO2-]
c. rate = k [NH4+] [NO-2]2
d. rate = k [NH4+]-1[N02-]
e. rate = k [NH4+] [NO2-]
