The data below were collected for the following reaction:

2NO2(g) + F2(g) -> 2NO2F(g)

[NO2 (M)] [F2 (M)] Initial Rate (M/s)
0.100 0.100 0.026
0.200 0.100 0.051
0.200 0.200 0.103
0.400 0.400 0.411

what is the rate constant, k?
I figured out that the rate law is Rate = k [NO2][F2] and not I feel like there is not enough
information to figure out the rate constant.

Thank you very much for all the help!

It's enough, you just plug in the numbers. From the first trial
Rate = k[NO2][F2]
.026 M/s = k (.1M)(.1M) and k = 2.6 M^-1 s^-1

The other trials give the same answer, after being rounded off.
