Consider the reaction of ammonium ions (NH4+) and nitrite ions (NO2−) shown in equation below: NH4+(aq) + NO2−(aq) → N2(g) + 2H2O(l)

Determination Number Initial [NH4+], M Initial [NO2-], M Initial rate, M/s
1 0.15 0.0075 3.0 X 10^-7
2 0.15 0.015 6.0 X 10^-7
3 0.30 0.015 1.2 X 10^-6

Required:
a. Use the method of initial rates to find the order of the reaction with respect to NH4+.
b. Use the method of initial rates to find the order of the reaction with respect to NO2−.
c. Calculate the rate constant, k for the reaction of NH4+ and NO2−.
