The reaction of nitrogen dioxide with fluorine 2NO2+ F2 NO2F is first order in N

Question

The reaction of nitrogen dioxide with fluorine 2NO2+ F2 NO2F is first order in NO2 and first order in F2 Complete the rate law for this reaction in the box below. Use the form klA]"[B]"..., where 'l' is understood for m, n ...(don't enter 1) and concentrations taken to the zero power do not appear. Rate = In an experiment to determine the rate law, the rate of the reaction was determined to be 9.59x10-4 Ms1 when [NO,]-2.26 M and [F2] 2.83 M. From this experiment, the rate constant is MM1s1 M's-1

Explanation / Answer

1)
Rate law is:
rate = k*[NO2]*[F2]

2)
rate = k*[NO2]*[F2]
Put values from 1st row of table in rate law
rate = k*[NO2]*[F2]
9.59*10^-4 = k*2.26*2.83
k = 1.50*10^-4 M-1.s-1
Answer: 1.50*10^-4 M-1.s-1
