Explanation / Answer

see experiment 1 and 3:

[F2] doubles

[ClO2] is constant

rate doubles

so, order of F2 is 1

see experiment 1 and 2:

[F2] is constant

[ClO2] becomes 4 times

rate becomes 4 times

so, order of ClO2 is 1

overall order = 1 + 1 = 2

Put values from 1st row of table in rate law

rate = k*[F2]*[ClO2]

1.2*10^-3 = k*0.1*0.1

k = 0.12 M-1.s-1

rate = k*[F2]*[ClO2]

rate =0.12*0.2*0.025

rate = 6.0*10^-4 M/s

Answer: 6.0*10^-4 M/s
