The rate law for the reaction in Exercise 20A.3(a) was reported as d[C]/dt=k_r[A][B][C]. Express the rate law in terms of the reaction rate v; what are the units for k_r in each case when the concentrations are in moles per cubic decimetre?

Data in Exercise 20A.3(a)

The rate of formation of C in the reaction 2 A+B→2 C+3 D is 2.7mol dm⁻³ s⁻¹. State the reaction rate, and the rates of formation or consumption of A, B, and D.
