This question is also leaving me in confusion

Determine the homolytic C-H bond strength in CH3OH employing the following data.
DfH (CH3OH) = -201.6 kJ mol-1
DfH (H) = 218 kJ mol-1
DfH (HBr) = -36 kJ mol-1
DfH (Br) = 111.9 kJ mol-1

CH3OH + Br
CH2OH + HBr k(300K) = 1 x 10^6 M-1s-1; k(350K) = 4 x 10^8 M-1s-1

CH2OH + HBr
CH3OH + Br k(300K) = 1 x 10^7 M-1s-1; k(350K) = 7.7 x 10^8 M-1s-1

My friend told me i gota make up serieas of chemical reactions and somehow use Hess's Law to caculute the C-H bond strength how am not sure? any help out thier will be much appreciated thankz!

I tried finding the steps for each reaction :S i gues its not workin out with me just confused of the actually question on what its Actually Asking. thanks

Did you figure out how to do it?
I'm assuming you're in my class, and I haven't figured it out yet and I'm kinda freaking out seeing as its due in an hour.
At least its only worth like 1.67% of our final mark.
