Two isomers (A and B) of a given compound dimerize as follows?
Both processes are known to be second-order in reactant, and k1 is known to be .270 L/mol(s) at 25 C. In a particular experiment, A and B were placed into separate containers at 25 C,where [A]o = 1.00x10⁻² M and [B]o = 2.50x10⁻² M. It was found that after each reaction had progressed for 3.00 min, [A]= 3.00[B]. In this case, the rate laws are defined as

rate = -Δ[A] / Δt = k1[A]²
rate = -Δ[B] / Δt = k2[B]²


a. calculate the concentration of A2 after 3.00 mins
