Question

Consider a hypothetical reaction A + 2B--->C, for which the following kinetic data were obtained
Experiment = [A] (M) = [B] (M) = Δ[C]/Δt (M/s)
1 = 0.20 = 0.10 = 7.0 x 10-5
2 = 0.40 = 0.10 = 7.0 x 10-5
3 = 0.20 = 0.20 = 2.8 x 10-4
a. Write the rate expression for the reaction.
b. What is the numerical value of the rate constant?
