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 0.15 L/mol·s at 25°C, where:

   

In a particular experiment, A and B were placed in separate containers at 25^oC, 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 half-life for the reaction involving A.

◦ 6.7 × 10² s
◦ 1.0 × 10² s
◦ 1.8 × 10² s
◦ 1.5 × 10³ s
◦ None of these are correct.
