Two isomers (A and B) of a given compound dimerize as follows:
    2A → A2
    2B → B2
Both processes are known to be second order in reactant, and k1 is known to be
0.25 L/mol·s at 25°C, where
    Rate = – = k1[A]2
In a particular experiment, A and B were placed in separate containers at 25°, where
[A]0 = 1.0 × 10–2M and [B]0 = 2.5 × 10–2M. It was found that [A] = 3[B] after the reactions progressed for 3.0 minutes. Calculate the concentration of A2 after 3.0 minutes.
Reference: Ref 12-15


2.8 × 10–22M
6.9 × 10–3M
3.1 × 10–3M
1.6 × 10–3M
None of these are correct.
