aaronq · Answer

Look at 2 situations where the concentrations of 2 of the species remain constant, for example:

situation 1 & 2, [A] & [B] are constant, therefore the rate is only dependent on [C].

[C] went from 0.1 to 0.2, so it doubled 
likewise, the rate went from 0.16 to 0.32.. so it doubled
$$rate=[C]^{m}$$
therefore m=1.
