Multiple Choice

Two isomers (A and B) of a given compound dimerize as follows:
 Two isomers (A and B) of a given compound dimerize as follows:    Both processes are known to be second order in reactant,and k<sub>1 </sub>is known to be 0.25 L/mol·s at 25°C,where   <sup> </sup> In a particular experiment,A and B were placed in separate containers at 25°,where [A]<sub>0</sub> = 1.0  \times  10<sup>-</sup><sup>2</sup> M and [B]<sub>0</sub> = 2.5  \times  10<sup>-</sup><sup>2</sup> M.It was found that [A] = 3[B] after the reactions progressed for 3.0 minutes. -Calculate the concentration of A<sub>2</sub> after 3.0 minutes. A) 2.8  \times  10<sup>-</sup><sup>22</sup> M B) 6.9  \times  10<sup>-</sup><sup>3</sup> M C) 3.1  \times  10<sup>-</sup><sup>3</sup> M D) 1.6  \times  10<sup>-</sup><sup>3</sup> M E) none of these

In a particular experiment,A and B were placed in separate containers at 25°,where [A]0 = 1.0 ×\times 10-2 M and [B]0 = 2.5 ×\times 10-2 M.It was found that [A] = 3[B] after the reactions progressed for 3.0 minutes.
-Calculate the concentration of A2 after 3.0 minutes.
