$aR \to bP, Rate = -\frac{1}{a} \frac{d[R]}{dt} = \frac{1}{b}\frac{d[P]}{dt}$

Hi Sarah,
When I did this problem myself, I determined the rate law to be k=[A][B]^2[C]^2. Given this, you can solve part c in two ways, by applying this equation to both the values of concentrations and initial rates for experiment 3 and experiment 4. Knowing that the rate constant is not dependent on concentration, it checks out that k is equal for both experiments regardless of the different concentrations in each.
